Mossos and Guardia Urbana prepare Barcelona for Halloween night: Preventive checks against calls for Blocus

For 31 October 2026, security forces in Barcelona have announced a preventive operational plan: intensive identity checks on public transport, checks at transport hubs and targeted searches in response to looming calls for Blocus.

Briefing

Barcelona is preparing a major security operation for the evening of 31 October 2026. The Mossos d'Esquadra and the Guardia Urbana have announced a «dispositivo de máximos», according to the authorities. It will take effect at 15:00 on Saturday and provide for a strong presence in the city centre and at key transport hubs. The aim is to prevent possible acts of violence, criminal damage and looting, following unrest in the city centre on 24 October.

Plans include widespread identity checks both on the streets and on public transport, searches to seize knives and pyrotechnic materials, and increased checks on people wearing masks or costumes. The police say this is in response to renewed calls circulating on social media and in Telegramchannels under the name «Blocus», urging people to gather at several locations around the city. The locations repeatedly mentioned in the notices include Plaça Catalunya, Arc de Triomf and Passeig de Gràcia ; two gatherings have been mentioned for the evening, from around 17:00, and another from about 20:00. The authorities warn that such information is liable to change and does not necessarily mean that gatherings will actually take place.

The operation’s command stresses its preventive aim and the principle of proportionality: the priority is to prevent potentially dangerous situations and protect businesses and passers-by. Business associations in the city centre have already taken precautions, with some shops installing protective materials or adjusting their opening hours.

Investigations are also continuing to identify the anonymous organisers behind the calls; in recent days investigators have shut down channels and arrested several suspects, including minors. How the night unfolds will depend on the situation on the ground; the authorities say they will deploy resources flexibly and adjust them if necessary.
