This is Yassine Mahi, the ex-convict who stabbed the police officer to death in Brussels: ‘I hate the police’

An ex-con who assaulted a guard in prison and was known as a ‘potentially violent extremist’. A man from an extremist family, whose brother may have gone to Syria. In the meantime, everyone in Belgium knows his name: Yassine Mahi (32), the Brussels resident who stabbed two police officers after announcing his hatred for police officers at the police station earlier in the day.
