A woman was punched on the London Underground earlier this month and police have now released an image of a man they want to speak to.

The victim was attacked at 1.45am on July 7 as a train approached New Cross Gate railway station.

British Transport Police said the woman is in her early 20s and suffered bruising to her eye.

A statement read: "Officers believe the man in the image may have information that could help their investigation.

"Anyone who knows him is asked to contact BTP by texting 61016 or by calling 0800 40 50 40 and quoting reference 54 of 07/07/19."
