The Operation Anubis was a police operation in Catalonia, Spain, initiated on 20 September 2017 by the Civil Guard following orders of the trial court number 13 of Barcelona, directed by judge Juan Antonio Ramírez Sunyer. Its aim was to dismantle the framework of the Catalan independence referendum of 1 October 2017, that was suspended on 6 September 2017 by the Constitutional Court of Spain as breaching the 1978 Constitution. Different headquarters of the Generalitat de Catalunya were searched and 14 people were arrested, including high ranking administrative staff, and company CEO's involved in the preparation of the referendum. Simultaneously, several printing and media companies were searched looking for ballot papers and boxes. More than 140 websites were shut down by Spanish authorities.

Crowds gathered around Catalan regional ministries to support those arrested and protest against the searches. About 40,000 demonstrators surrounded the Catalan economy department heeding a call made by pro-independence groups Òmnium Cultural and ANC. One vehicle of the Civil Guard was damaged. The autonomous police force of Catalonia, Mossos d'Esquadra, recognized that there was a risk situation.

Jordi Sànchez and Jordi Cuixart—leaders of ANC and Òmnium Cultural— and the Mossos d'Esquadra Major Josep Lluís Trapero Álvarez have been accused of sedition, a felony regulated by the article 544 and subsequents of the Spanish Criminal Code, for allegedly encouraging protesters to hinder the Spanish police raids to dismantle the framework of the referendum. On 16 October 2017, Sànchez and Cuixart were provisionally put into jail without bail pending the investigation. At the conclusion of the trial of Catalonia independence leaders on 14 October 2019, the Spanish Supreme Court condemned Sànchez and Cuixart to a nine-year sentence after considering them guilty of sedition.Catalan separatist leaders handed jail terms for independence bidSentencia del ‘procés’: penas de 9 a 13 años para Junqueras y los otros líderes por sedición y malversación Amnesty International stated their detention and sentence constitutes a disproportionate restriction on his rights to free speech and peaceful assembly, and urged Spain to free them. The nine jailed leaders were pardoned and freed in June 2021.

Background The investigation started due a complaint presented by the far-right political party Vox and an anonymous complainant, in response to a claim from Catalan judge and politician Santiago Vidal assuring that preparations for the referendum were underway. The investigation was assigned to the trial court number 13 of Barcelona, which had a conservative judge, Ramírez Sunyer, close to the General Council of the Judiciary. According to the defense, the assignment was against the rules and was done arbitrarily to get a hard anti-independence judge to investigate the case.

On 9 September, Spanish Civil Guard raided the headquarters of the weekly newspaper El Vallenc for being allegedly linked to the preparation of the independence referendum, about 200 people gathered in front of the building to support the journalists being investigated. On the same day, the Civil Guard also raided the printing office Indugraf Offset in Constantí searching for ballots and material related to the Catalan referendum.

Over 45,000 notifications for the polling station members were confiscated on 19 September by the Civil Guard after raiding the offices of the posting service Unipost. Hundreds of protesters practiced nonviolent resistance sitting in front of the offices in order to block the access, delaying the action of the judicial committee for hours.

20 September Following a judge's orders, on the morning of 20 September 2017 several units of the Spanish Civil Guard raided 41 locations, including: the headquarters of the Vice President of Catalonia, the regional ministries of economy, foreign affairs, social affairs and family, the tax agency of Catalonia, the consortium of open administration of Catalonia, the Catalan Institute of Finance, the dotCAT Foundation, private houses of Catalan government officials and one printing company. Spanish officers claimed to have seized 9.6 million ballot papers in the raids.

During these raids the Spanish Civil Guard arrested 14 people, most of them high-ranking members from the Generalitat of Catalonia, but also CEOs of private companies or just administrative staff.

After hours of watching it, officers of the National Police Corps circled the headquarters of the Popular Unity Candidacy party (CUP) at 1:00pm, in Casp street, Barcelona, but were prevented from searching inside by party members and supporters due to not having a court order. The party made several calls to the citizenship to "go to protect our headquarters" and organized a sit-in protest in order to block Spanish police access to their offices which gathered thousands of people. The police deployment lasted eight hours until they finally left without searching the building or arresting anyone. David Fernàndez, member of CUP, defined the intend to enter their headquarters without a court order as a "flagrant crime against fundamental, civil and political rights".

On the same day, the Spanish government announced that they were sending two ships to Barcelona and one to Tarragona to allocate Spanish police reinforcements deployed from other places of Spain. The first ship to arrive in Barcelona was the Rhapsody, from an Italian shipping company, followed by the MS Moby Dada, also Italian. The ship that docked in Tarragona was named GNV Azzurra. The three ships had a capacity of 6,600. Days later, these reinforcements tried to prevent the referendum on independence, injuring over 900 voters and panic scenes that were broadcast on news stations worldwide.

Protests

As the searches began, crowds spontaneously gathered outside the buildings being raided by the Spanish Civil Guard; namely the headquarters of the Department of Economy, in Rambla Catalunya, and the Department of External Affairs, in Via Laietana.

Some minutes later, Òmnium Cultural and ANC called for a mobilization to avoid demonstrators being prosecuted given that Spanish Citizen's Security Law sets very high penalties for unauthorized demonstrations. Civil pro-independence organizations called for "peaceful resistance" in front of some of the buildings being searched. The Mayor of Barcelona Ada Colau also called all citizens to take the streets in protest for the raids. Soon after people started gathering in front of the Economy Department, crowds forced the closure of the Gran Via. According to several sources, at some moment there were more than 40,000 people in the demonstration in front of the Catalan economy department. In the afternoon, various volunteers offered food and water to demonstrators. Several concerts were held in the junction between Rambla de Catalunya and Gran Via, like Companyia Elèctrica Dharma and Judit Neddermann as well as castells.

Even though the police operations were not notified in advance to the autonomous police force of Catalonia, Mossos d'Esquadra, as soon as people started gathering around the Catalan economy department, Civil Guard requested the intervention of Mossos. The Civil Guard agents involved in the raid made 6 calls for help to Mossos during the day. The first request for help was at 9:14 am with the subject: "Urgent - Request for support to Mossos" with the goal to force people to move 40 meters away from the building. Mossos did not intervene alleging that might cause public disorders and that the demonstration was being peaceful and authorized. Instead, ANC volunteers created a human corridor so the access to the building would not get blocked. Workers of the Department of Economy hung Catalan and European Union flags in the balconies of the building as long as the raid lasted. Mossos alleged they were not notified in advance about the raids, so they couldn't prepare a police operation to keep demonstrators far from the building. At midday, the Civil Guard notified Mossos they would end the registries around 20.15, but later stated they would be delayed for hours due to computer problems. Mossos considered there was a situation of risk, but discarded using crowd-controls units until later in the night when most demonstrators already left.

According to the court clerk, she remained trapped until midnight inside the building and had to flee by the roof terrace, while several agents were trapped throughout the night as demonstrators shouted outside "You won't get out!" and "They shall not pass". The solution to leave through the roof terrace of the neighbouring building was proposed by Mossos after the court clerk rejected to use the human corridor created by the police. Civil Guard stayed inside the building until the demonstration was called off and Mossos cleared the zone, so they could get access to the three cars that were parked in front of the Catalan economy department. Those cars were damaged by journalists in the morning and later vandalized up by demonstrators. According to the Civil Guard, the damages in the vehicles (3 Nissan Patrol) accounted for €135,632 .

Civil Guard officers left unguarded weapons and ammunition inside the cars, which were left with the doors unlocked and were later surrounded by demonstrators. The Mossos were not informed that the cars contained weapons until the afternoon, at that point, the Mossos used a helicopter to verify that no demonstrator entered inside the cars. Eventually, the leaders of ANC and Òmnium, Jordi Sànchez and Jordi Cuixart, were notified there were weapons inside the cars too. At that point, ANC volunteers expanded the human corridor and left the cars inside the corridor, so demonstrators had no access to them. An investigation from the newspaper El Món in 2019, reported that none of the Civil Guard officers that left unguarded weapons inside the cars was sanctioned by the Spanish Ministry of the Interior.

Jordi Sànchez and Jordi Cuixart —leaders of ANC and Òmnium Cultural— and the Mossos d'Esquadra Major Josep Lluís Trapero Álvarez have been accused of sedition, a felony regulated by the article 544 and subsequents of the Spanish Criminal Code, for allegedly encouraging protesters to hinder the Spanish police raids to dismantle the framework of the referendum. Sànchez and Cuixart have been provisionally put into jail without bail pending the investigation.

Besides the demonstration in Barcelona, multiple protests took place in other cities across Catalonia; including cacerolazo during the night. Several Spanish cities also organised demonstrations against the police operations.

In Gran Teatre del Liceu, Barcelona an audience at the representation of Il Viaggio a Reims sang the Catalan anthem, Els Segadors, and shouted pro-Catalan independence slogans.

Reactions Dozens of Catalan organizations and entities condemned the jailing of Catalan officials and made calls to respect "democracy and freedom of speech" in Catalonia and asked all citizens to "defend Catalan institutions". Those entities included all Catalan public universities (UB, UAB, UdG, UPF, UdL, URV, UPC, UOC), the biggest Catalan workers and students unions including CCOO and UGT, sport clubs like FC Barcelona and Girona FC, more than 20 professional associations, the Confederation of Neighborhood Associations of Catalonia, NGO's like FundiPau, music festivals like Primavera Sound and cultural organizations like Fundació Antoni Tàpies.
