London attack: British-born attacker ‘known to MI5’
The Westminster attacker was British-born and known to the police and intelligence services, Prime Minister Theresa May has revealed.
She told MPs he had been investigated some years ago over violent extremism, but was "peripheral" and was not part of the current intelligence picture.
The so-called Islamic State group has said it was behind the attack.
