The victim, a woman in her late teens, was approached by a man at Waterloo station at around 2:30pm.

The man initially asked for help but then proceeded to follow the female when she ignored him. He then grabbed her arm, brought the victim to a ticket machine and made her purchase a top-up for his Oyster card.

He then forced her to board a Jubilee line to Westminster Tube station where the victim was able to alert station staff between 3:45pm – 3:50pm.  As she did this the suspect walked away and exited the station.

Officers believe the man in the CCTV images may have information that could help their investigation.
