Police deployed riot-control units after groups moved through central Palma during clashes near Plaza de España on Friday evening, 30 October. Several shops shut early and covered their windows to guard against possible damage. Diario de Mallorca reported that the square was initially calm, with three police vans nearby; officers were stopping young people and searching their backpacks.
Incidents began after 19:30, when members of Núcleo Nacional arrived at the square where people were camping. Some of those gathered shouted «¡Aquí están los antifascistas!» and «¡Fuera fascistas de nuestras calles!». Groups of young people also repeatedly called for Pedro Sánchez to resign, prompting renewed chants from far-left activists. The Blocus-related gathering had been promoted anonymously through Социальная сеть and had not been notified to the Government Delegation.
The National Police sent officers from its Unidad de Prevención y Reacción (UPR), with officers and vans positioned around the square. Police Local officers blocked a large group on the road connecting Plaza de España with Sant Miquel amid concern about possible vandalism along one of Palma’s main shopping streets. The account does not report injuries or arrests. By about 22:30, however, the Majorca Daily Bulletin reported that a large police deployment had contained incidents and that one person under 18 had been arrested for allegedly throwing stones and bottles. The same report said police formed a cordon around the housing-rights camp in Plaça Espanya after an object was thrown. Officers also blocked Carrer de Sant Miquel and Carrer dels Oms after fireworks were set off and a stampede occurred.
Europa Press reported that National Police identified and fined six minors during the preventive operation. Police sources said officers found corrosive material and aluminium foil among items carried by the youths, as well as a simulated weapon; the report did not say the items had been used in an attack. The minors were taken to National Police headquarters in Palma and later handed over to their parents. Europa Press also reported that no formal protest ultimately took place at Plaza de España.
Shops in the area brought forward closing times and used boards or other protective measures on their windows. Concern had risen after several days of threats circulated on social media and a call to gather in central Palma. Some retailers boarded up windows. Palma City Council placed local police on alert and coordinated with other security forces, while also requesting additional resources from the Government Delegation.
The call was said to have come from the Blocus collective, but the account does not attribute direct responsibility for the clashes to Blocus. Before the gathering, National Police said they had not detected organized Blocus groups in Palma and described the planned operation as proportionate to the identified risk, without extraordinary reinforcements. The security preparations followed disturbances reported in central Barcelona the previous weekend and included plans for deployments of different sizes depending on developments. A separate Blocus report from Valencia concerns alleged plans for shop raids and is not identified as connected to the Palma unrest.
The account said the police alert was to continue on Saturday amid Halloween and social-media calls for vandalism. National Police also urged calm amid online calls for counter-protests, telling people not to take the law into their own hands. Police presence was expected to continue into the early hours of Saturday.
