Hashem Abedi, convicted for his role in the 2017 Manchester Arena bombing, attacked three prison officers with boiling cooking oil and homemade weapons at HMP Frankland, resulting in life-threatening injuries. The incident, described as “unprovoked” and “vicious,” drew condemnation from justice secretary Shabana Mahmood, who emphasized the need for strict punishment for violence against prison staff. Following the assault, the Prison Officers’ Association called for a review of privileges for terrorist offenders, advocating for stricter controls over their access to potentially dangerous items.
