Knife maniac kills ex-girlfriend

London's Euston station becomes bloodbath as knifeman stabs ex-girlfriend.

Horrified rush hour commuters watched as the attacker brutally murdered his ex, stabbed a would-be saviour and ran up busy escalators before slitting his own throat and stabbing himself in the chest.

Paramedics managed to remove the knife from the man's ribcage and he is being treated at the University College Hospital.
