A TEENAGER has been traumatised after being raped in the toilet of a Fareham-bound train.

The attacker, thought to be aged about 20, is then believed to have got off the train from Cardiff at Southampton.

CCTV footage from Southampton Central station is being studied by British Transport Police.

The attacker moved to sit beside her on the train before bursting in when she went to a toilet.

Police say the rape took place on Saturday between 3pm and 4pm. The girl was left traumatised. Detectives were due to interview her later today.

Det Insp Philip Kent, based at London Bridge, is leading the hunt and is liasing with colleagues in Southampton and also with Hampshire police.

He said: "During the journey the suspect was sitting, first of all, in the vicinity of the victim and then he moved to sit next to her. We know they were in conversation during the journey before the offence took place."
