Detectives are looking to find a man after a knifepoint robbery in Westminster left a victim severely shaken.

Police say the victim, a 31-year-old woman, was waiting at a bus stop in Boundary Road at the junction with Finchley Road, when the suspect approached her.

Uneasy at his sudden presence, she moved away from him.

After a few moments, he "lunged towards the victim with a knife in his hands", according to Metropolitan Police reports.

He then held the knife to the victims' upper body and demanded that she hand over her possessions.

The victim handed over her bag containing her mobile, purse and other items and the suspect then fled the scene and ran down Boundary Road.

Detective Constable Jonathan Bradshaw said: "This was a frightening incident on a lone woman as she was making her way home.

"Despite this happening some months ago the victim still remains shaken by the incident and is fearful of being out by herself.

"The robbery took place on the borders between Westminster and Camden and I believe that the man responsible is possibly someone who lives locally or knows the area quite well.

"We're keen to hear from anyone who recognises the man in the e-fit or anyone who has any information that could assist us with our inquiry."

The suspect is described as a black man, aged between 17 to 21-years old, approximately 5ft 8ins tall and of skinny build.

He was wearing a loose-fitting, dark-coloured jacket with a hood and dark jeans. He also is said to have a deep voice.

Anyone with any information is asked to contact Westminster CID on 101 or Crimestoppers anonymously on 0800 555111.
