A woman has been sexually assaulted while waiting for a train at Euston Station. The 56-year-old woman was standing near the departure boards around 9:15pm on Monday 23 September, when a man approached her. Police have released CCTV images of man they are trying to trace.
PC Dionne Lyon from British Transport Police said: "A man came up from behind and inappropriately touched her. He then tried to make a conversation with her, at which point she walked away towards a Milton Keynes-bound train.
"He followed her onto the train and began to stare at her during the journey, making her feel uncomfortable. He is also believed to have touched another woman during the train journey, before a train guard ejected him from the train at Hemel Hempstead for his behaviour."
