Do you recognise this man?
British Transport Police (BTP) detectives need to speak to him in connection with a sexual assault on a train travelling between Prittlewell and Southend Victoria station in the early hours of Friday, July25.
Detective Constable Paul Cudby said: “The victim, a 23-year-old woman, boarded the 12.50am service from Liverpool Street to Southend Victoria.
She fell asleep but was awoken by a man sexually assaulting her.
Both the victim and her attacker left the train at Southend Victoria station, and the man left the scene.
Following an appeal for information in the Southend area, officers are now looking further afield for information.
DC Cudby added: “We now believe the man boarded a train from Shenfield to Prittlewell before getting onto the train with the woman.
“We are also looking into the possibility he may have made his way to Shenfield from east London.
“We have analysed onboard CCTV footage of the incident and are keen to speak to the man in the pictures.
“I am confident he has key information on this assault.
“This was an extremely frightening experience for the victim and we need to find the person responsible for this assault as soon as possible.”
