Hashem Abedi, the brother of the Manchester Arena bomber, was allegedly like ‘a silent assassin’ as he left three prison guards with burns, scalds and stab wounds. The officers suffered injuries at HMP Frankland in County Durham after Abedi attacked them with hot cooking oil and ‘home made weapons,’ the Prison Officers’ Association alleged.

Abedi has been moved to the only available highly-controlled 'suite' cell in the country - a standalone self-contained unit monitored by a minimum of five people at any one time, and a prison dog. There are only four such cells across England and Wales.
