Police are searching for a man after a woman was sexually assaulted on a rush hour Jubilee Line train last month.
The incident took place at 6.10pm on March 14 on a crowded eastbound Jubilee Line train from London Bridge to Canning Town.
The man is alleged to have stood close to a woman and sexually assaulted her.
When the woman challenged him, he fled the train at Canning Town and got on a westbound service.
Releasing an image in an appeal, British Transport Police officers said they believe the man pictured may have information that could help their investigation.
Anyone who recognises him or has further information is asked to contact the force by texting 61016 or by calling 0800 40 50 40, quoting reference 531 of 14 March.
Alternatively, call Crimestoppers anonymously on 0800 555 111.
