POLICE are looking for a man who indecently exposed himself onboard a train.

British Transport Police have issued a CCTV image of a man they want to trace following the incident on a train between Hither Green and New Cross on August 15 at around 7.40pm.

Investigating officer PC Laura Mackley said the flasher had sat diagonally opposite his 21-year-old victim and asked her for the time.

PC Mackley said: “The victim responded but the man repeated his question a second time. When the victim looked up she noticed that the man had exposed himself.

“She then confronted him about his behaviour before immediately moving to another carriage.”

The man left the train when it arrived at New Cross.

PC Mackley said: “This was an intimidating experience for the victim and we are determined to do all we can to catch the person responsible.”

Anyone with information should call 0800 405 040 or Crimestoppers on 0800 555 111.
