A man sexually assaulted a woman on a tube station escalator after following her from the train.

The victim was on a Northern Line train at around 9.45pm on Sunday, February 18 when a man boarded the train at Archway and sat a few seats away.

The victim left the train at Warren Street and, as she got up to leave, noticed the man leaving ahead of her.

He then stopped to get behind the victim, followed her off the platform, and sexually assaulted her on the escalator, British Transport Police (BTP) said.

BTP officers believe the man in the image may have information that could help their investigation.

Anyone with information should contact the British Transport Police by texting 61016 or by calling 0800 40 50 40, quoting reference 120 of 19/02/2024.
