On Tuesday 10 November, late in the afternoon, officers made a significant cannabis seizure in building MAH2 of Riom prison.[1] At about 3:30 p.m., after an exercise-yard round, supervisors ordered pat-down searches at the exits from walks and movements following suspicions.[1] One detainee tried to get rid of something, but officers directed him to a search room.[1] A full body search found just under 450 grams of cannabis on him.[1]

The union says it was one of the largest seizures since the facility opened in 2016.[1] The union puts total drug seizures at the prison at 7.1 kg up to 30 September 2026 and 11.5 kg in 2025.[1] The local FO Justice union called on the prison management to impose a dissuasive sanction.[1] It also called on the prosecutor’s office for a penalty matching the trafficking involved.[1]
