Overview

• The 28-year-old appeared via video link from HMP Belmarsh at Woolwich Crown Court, flanked by five prison officers.
• He was not required to enter pleas to the charges, with the next appearance scheduled at the Old Bailey on 17 October.
• Prosecutors have charged him with three counts of attempted murder, one count of assault occasioning actual bodily harm, and one count of unauthorised possession of a knife or offensive weapon.
• The charges relate to an April 12 incident at HMP Frankland in which four officers were injured in a suspected ambush, with three taken to hospital with serious injuries.
• A planned appearance at Westminster Magistrates' Court the previous day was canceled after a burst water main left the building without water and forced its closure.
