Police are seeking a man after a woman was sexually assaulted on the top deck of a bus travelling between Crayford and Bluewater.

Between 9.30am and 9.45am on Tuesday, February 4, a 20-year-old on the Route 492 became aware of a man coming up to the upper deck and sitting directly behind her.

She then became aware of pressure to her side. The man then proceeded to touch her inappropriately.

The victim moved to another seat, but the man continued to touch her until she left the bus.

Detectives have released the image of a man they are urgently seeking to identify.

Detective Sergeant Ian Beattie, from the Met’s Roads and Transport Policing Command, said: “This was an incredibly upsetting incident for the victim.

"I would ask anyone who recognises this man to get in touch with us as soon as possible.”
