A MAN sat behind three women on a train and touched himself inappropriately.

Between 4.05pm and 4.15pm on July 26 a man boarded a train at Twyford Station and sat behind a 48 year-old woman from Reading and two other woman.

He proceeded to expose himself and then perform a sex act, on himself.

A spokesperson for British Transport Police said: "This was clearly a shocking and distressing experience for the victim and our priority is to make sure the person responsible is traced and brought to justice.

"We are also urging any potential witnesses to come forward, and are particularly keen to hear from the two women sat near the man.

"We believe they may have been speaking Polish and it is vitally important we speak to them, as they may have seen or heard something that could prove crucial to this investigation."
