A TEENAGE man was sexually attacked on train travelling between Didcot and Reading.

The victim was left 'shocked' after another man on the same train, who boarded at Didcot Parkway, groped him with both hands before exposing himself.

British Transport Police has issued an appeal for information, and believe the man pictured above might have information about what happened.

The sex assault happened at about 3.45pm on Thursday, September 5.

The victim was approached at Didcot station by the other man, who asked him if the train was heading towards London.

They both joined the GWR train when it arrived, and as the train approached Reading station, the man approached the victim again and carried out the assault.

A statement released by police said: "The victim quickly left the service at Reading, but was left understandably shocked by the man's invasive behaviour."

The other man remained on the train, leaving at Paddington. 

Police have asked anyone who knows the man pictured to contact BTP by sending a text to 61016, calling 0800 40 50 40, or Crimestoppers anonymously on 0800 555 111.
