# Blocus network activity and law enforcement crackdown in Spn > Developing situation record from CLSTR: https://clstr.news/situations/blocus-network-activity-in-spain > Updated: 2026-10-31T21:12:15.000Z. Sources: 145. Developments: 5. Following reports from technology firm Golden Owl regarding the ‘Blocus’ network, Spanish law enforcement has intensified operations to dismantle the movement. Coordinated actions by the National Police, Civil Guard, and Mossos d’Esquadra have led to numerous arrests across Valencia, Barcelona, Bilbao, Málaga, and Tenerife. Among those detained is a 20-year-old man in Picanya, Valencia, identified by investigators as the movement’s founder in Spain. He is accused of managing encrypted communication channels on Telegram and WhatsApp to coordinate looting, sabotage, and violent confrontations. In Catalonia, the Mossos d’Esquadra arrested a 21-year-old in Cabrera d’Anoia for allegedly acting as an instigator and communicator, alongside several other minors. In response to calls for unrest, businesses in Madrid, Valencia, Barcelona, Bilbao, and San Sebastián reinforced storefronts. Recent security deployments in Madrid and Barcelona successfully prevented major incidents during calls for Blocus protests. In Madrid, approximately 1,700 municipal agents and National Police units monitored high-traffic areas like Gran Vía and Plaza de España. Many businesses utilized protective panels or early closures, and planned demonstrations in the capital lost momentum without resulting in confrontations. In Barcelona, the Mossos d’Esquadra activated a level 4 security protocol, the highest level for public demonstrations, following previous unrest where over one hundred people, many of them minors, were detained. While tensions remained in areas like Lleida, the period passed without significant social chaos. Violent disturbances, including looting and property damage, have recently occurred in cities such as Barcelona, Avilés, and A Coruña. Experts indicate these movements are organized via WhatsApp and Telegram, where digital channels provide instructions on attire, such as black clothing and balaclavas, to target luxury goods and technology stores. Some unrest appears inspired by protest models in France. ## Claims - Recent disturbances in Barcelona resulted in 133 arrests, with 85 being minors.
