British Transport Police are appealing for information after a man exposed himself on the Docklands Light Railway.

A 48-year-old woman was travelling from Canary Wharf at around 8.30pm on Friday, January 3 when a man sat opposite her.

He exposed himself and carried out an indecent act at Island Gardens before leaving the train at Cutty Sark.

A CCTV image has been released of a man the police believe may have information about the incident.

PC David Udomhiaye said: “This was an intimidating and upsetting experience for the victim.

“We don’t tolerate unwanted sexual behaviour of any kind on the transport network and take all reports seriously.

“I’d urge anyone who recognises the man pictured to come forward and speak to officers investigating the incident.”

Anyone with information should call British Transport Police on 0800 40 50 40, or text 61016, quoting background LUA/B6 of 17/03/14, or call Crimestoppers anonymously on 0800 555 111.
