Westminster Bridge terrorist took steroids before he killed four pedestrians with his car then stabbed police officer to death in Parliament

Westminster jihadi Khalid Masood took steroids before he mowed down four pedestrians and stabbed a police officer in the horrific terror attack.

Masood, 52, was shot dead by police after he drove a rental car into pedestrians on Westminster Bridge before fatally stabbing PC Keith Palmer, 48.

Masood, who was born in Kent, may have taken performance enhancing drugs hours before he launched the rampage on Westminster Bridge, a pre-hearing inquest at the Old Bailey was told.
