A witness appeal has been launched after a 22-year-old woman from Sittingbourne was sexually assaulted.

The attack happened outside London Victoria railway station at around 5.10pm on Friday, October 9.

Detectives have made an arrest but British Transport Police is appealing for witnesses to come forward with any information that could help with the investigation.

BTP Detective Constable Andy Parkinson, the investigating officer, said: "The victim, a 22-year-old woman from Sittingbourne, was followed across Victoria station by the suspect who persisted in attempting to engage her in conversation.

"Despite her telling the man to leave her alone, he forced himself on her, touching her indecently."

The attack occurred in the forecourt area to the right of the main entrance arch by the rear of the Iron Duke Public House.

The attacker immediately fled the scene following the incident and the victim returned to the station to report what had happened.

DC Parkinson added: "We are working to establish the exact circumstances of what happened outside the station and are appealing for anyone who witnessed the incident or has any information that may help our investigation to come forward and contact police.

"Victoria is a very busy place, especially at this time of the day, so there would have been plenty of people about who will have seen something.

"I am especially keen to speak to a female passenger who the victim reported the matter to as she re-entered the station. She is believed to have been catching a train on platform two heading toward the Medway, Dover and Ramsgate areas."

A 37-year-old man, from Thornton Heath, was arrested on Thursday, October 15, on suspicion of sexual assault and has been bailed to return to BTP in late December.
