A woman in her mid-20s who was walking through an alleyway in Chiswick was sexually assaulted twice by a man who pursued her on a bike.

On Wednesday, March 14, between 5.40am and 5.50am, a woman in her mid-20s was walking through an alleyway which runs between Barnes Bridge and Chiswick station.

A man on a bicycle spoke to her as he passed and then returned. He then approached the young woman and molested her, before she pushed him and ran away.

However, the man pursued the victim and caught her, carrying out another sexual assault.

Releasing an e-fit image, detectives from Met Police said the suspect is described as a black man, approximately 6ft and aged between 25 and 35.

At the time of the offence, he is thought to have been wearing a dark beanie hat and a dark, thick sports jacket, a police spokesman said on Wednesday (June 6).
