Police have begun their hunt for a topless man after a woman was sexually assaulted on a London Underground train.
The horrifying attack happened on a Jubilee line train travelling between the Southwark and London Bridge stations, on Monday, June 30.
In an especially disturbing turn, the suspect struck just before 5pm - during rush hour, when passengers might especially expect to be safe amid crowds of commuters.
British Transport Police (BTP) officers are now looking to speak to another man who they believe might have information which could help their investigation.
They have now released a CCTV image of the person of interest in the hope members of the public might recognise him and be able to identify him.
