HATED private security firm G4S suspended nine members of its staff at a detention centre yesterday following allegations of abuse and assault, sparking fresh condemnation of Britain’s “broken” immigration system.

An investigation has been launched after the BBC’s Panorama claimed it had undercover footage of officers “mocking, abusing and even assaulting detainees” at Brook House Immigration Removal Centre, near Gatwick.

The programme said it had also found “widespread self-harm and attempted suicides” at the facility and that drug use there is “rife.”
