Police are hunting for a man after a woman was sexually assaulted at a City Tube station.
British Transport Police said the attack happened last summer at Moorgate Tube station.
A CCTV image has now been released, five months after the alleged attack on August 21 last year.
The shaven-headed man is seen in the image standing on a Tube carriage while holding a mobile phone.
He is wearing dark trousers, a sleeveless hooded top, and he has a distinctive necklace draped around his neck.
“Officers investigating a sexual assault at Moorgate underground station are today releasing this image in connection”, BTP said in a statement.
“At around 11.15am on 21 August, a man sexually assaulted a woman on the Northern line platform.
