Five people were arrested Wednesday in connection with the killing of Sid-Ahmed Moualek, who died following an assault at Montreal’s Bordeaux Detention Centre in April 2025.

Investigators with the Sûreté du Québec’s (SQ) Personal Crimes Investigation Unit made the arrests as part of their ongoing investigation into the case.

On April 28, 2025, Moualek, 22, was attacked in a common area of the prison. He was taken to hospital but died from his injuries approximately 10 days later.

The five suspects are scheduled to appear by videoconference at the Montreal courthouse on Thursday. They could face multiple charges, including first-degree murder, conspiracy to commit murder, and aiding and abetting.

The investigation remains ongoing. Anyone with information is asked to contact the SQ’s Criminal Information Centre.
