Police are trying to find a woman who twice tried to gain access to a “highly restricted area” in Westminster before dumping two large knives nearby.

A CCTV image and footage have been released by police seeking the public’s help to identify the woman following the “suspicious behaviour” back on February 24.

The Met Police said: “At around 3.30pm a woman asked a police officer for access to a highly restricted area, but was refused.

“Detectives believe this is the same woman recorded on a nearby CCTV camera at around the same time.

“Ten minutes after her first approach she returned to the secure area but again did not gain admission.

“Later a scarf, police believed to be carried by the woman, was found on a nearby wall wrapped around two large knives.”

This is not being linked to any other incidents, police say.

If you think you know who this woman might be call officers on 020 7161 6216 or 101.
