The stability of Catalonia’s prison system has come under intense scrutiny following the exposure of an alleged Catalan prison smuggling network at Quatre Camins prison. The Mossos d’Esquadra are currently investigating a network involving prison officials suspected of smuggling prohibited items-ranging from mobile phones to narcotics-to inmates on behalf of a powerful criminal organisation.
The investigation intensified after a public employee was arrested at the facility while attempting to smuggle banned substances inside. Authorities link this incident to a notorious mafia clan based in the La Mina neighbourhood, located on the border between Barcelona and Sant Adrià del Besòs.

The ‘La Mina’ Clan Connection
The criminal group at the centre of the inquiry is described as a local clan with significant influence across the Catalan penitentiary system. Intelligence suggests they are among the most dangerous groups currently incarcerated in the region. The clan’s leader, who was serving time at Quatre Camins, has since been transferred to Brians 2 prison alongside the detained official.
Investigators believe the clan exerts considerable pressure within the prison walls, allegedly employing blackmail or extortion to coerce staff and other inmates into serving their network. The operation focused on a transactional system where officials would deliver practically any requested item to the gang members.
Controversy Over Inmate Governance
The case has highlighted potential flaws in the specific management model used in Catalan prisons. The clan leader held the position of ‘president’ within an MR1 module-a residential unit designed for participation and coexistence (MPIC). These modules are intended to grant inmates greater autonomy and responsibility.
Despite his leadership role, the inmate allegedly used his status to avoid standard searches and interventions. Sources close to the investigation state that he threatened to resign his representative post if subjected to the same regulations as other prisoners. Although prohibited items were found in his possession on multiple occasions, he was not removed from his position, raising serious questions about internal oversight.
“This is not an anecdote or an isolated error, but further evidence of the collapse and failure of the Catalan prison model, based on an ideological conception of participation,” stated prison sources.
Rising Violence and Union Outcry
Union representatives argue that the current administration’s approach-often criticised as overly permissive-prioritises the appearance of inmate rehabilitation over genuine security. They claim that placing inmates with serious criminal records in positions of authority without rigorous vetting compromises the safety of both staff and the prison population.
The scandal comes amidst a sharp rise in violence against prison staff. In 2025, assaults on officials rose to 699, up from 607 the previous year. It is worth noting that despite this increase in prison violence, Barcelona’s overall crime rate fell by 6.1% in 2025. Workers are demanding an immediate review of the prison model, calling for stricter filters for inmate representatives and an increase in human and material resources.
Following the exposure of the network, the clan leader has been placed in an isolation cell at Brians 2. The implicated official was initially held in preventive detention at Brians 1 but has reportedly requested a transfer to a secure unit at Quatre Camins.
