LONDON: British riot police on Friday (Saturday) regained control of a prison after more than 300 inmates took part in a “serious disturbance” that led to a partial lockdown. A specialist “Tornado Team”, which handles prison riots, was sent in to deal with the incident at the privately run prison in Birmingham, central England. The team were sent in at 8:35 p.m. local time, and the four wings affected were brought under control shortly after 10:00 p.m., according to a Ministry of Justice statement. All prison staff were accounted for, with no reported injuries, while one prisoner required hospital treatment. “This was a serious situation and a thorough investigation will now be carried out,” said Justice Secretary Elizabeth Truss. Security firm G4S, which runs the facility, earlier said a “disturbance” had spread from two prison wings to four during the day. Local media reported that trouble flared when a security guard was threatened with a syringe by one inmate while another took his keys.
