Police hunt woman with knives
A woman who twice tried to gain access to a "highly restricted area" in Westminster before dumping two large knives nearby is being sought by Scotland Yard.
Detectives have released CCTV video footage of what they believe is the same woman pacing behind iron gates on two occasions.
After being refused entry, a scarf the woman was believed to be carrying was found on a wall wrapped around a pair of knives.
Scotland Yard last night made an appeal to trace the woman on BBC One's Crimewatch, after the incident over five months ago.
A statement said: "A woman asked a police officer for access to a highly restricted area, but was refused."
It is not being linked to any other incidents, police added.
