Police are looking to trace the man pictured, whom police would like to speak to in connection with an alleged sexual assault in Elephant and Castle Tube Station.
The incident was said to have happened at about 12.30am on March 28, on the northbound Northern Line platform.
The victim – a 26-year-old woman – was walking along the platform when she passed a man who was seated on a bench. When she walked past him, the man stood up, grabbed the woman and sexually assaulted her.
Investigating officer PC Louise Wilmot, of British Transport Police said: “Understandably this was a very frightening experience for this woman – it was unexpected and highly inappropriate. We will not tolerate behaviour such as this and will always take firm action against perpetrators.
“I would like to hear from anyone who can help us identify this man. If you know who he is, please get in touch as your information will help us investigate.”
Anyone with information can text BTP on 61016 or call 0800 40 50 40 quoting reference 354 of 25/04/2017. Alternatively, pass information anonymously to Crimestoppers on 0800.
