London train sex attack: 16-year-old girl assaulted by man on journey from Kings Cross

Police have released an image of a man they want to speak to in connection with a sex attack on a teenage girl on a train from Kings Cross St Pancras to St Albans City. The 16-year-old was touched inappropriately as she travelled on the 11.38pm train out of London to Hertfordshire on Friday 6 May 2016.

The victim took a photo of her attacker, who was sat opposite her on what appears to be a busy train carriage.

A British Transport Police statement said: "She [the victim] sat opposite a man, who made inappropriate physical contact with her during the train journey before he departed at St Albans City station. Officers think the man in the photo might have information that could help the investigation."

In March, IBTimes UK revealed St Pancras was the most crime-ridden train station in London after 840 recorded offences were committed there last year .

The station topped the list of offence rates in the city ahead of Victoria and Euston.
