A 14-year-old girl was raped twice in one night by two separate attackers, one of whom she flagged down for help, police say.

Authorities in Birmingham have launched a major investigation after the girl was subjected to a “horrifying ordeal” on Tuesday night.

She was reportedly with a friend at Witton train station at about 7pm when a man approached her and led her to a secluded area, before raping her.

Shortly after the attack, the victim walked away from the area and flagged down a passing car to ask for help at about 2am.

Police say when she got into the vehicle she was raped for a second time by what is believed to be a second offender.

The girl then returned home and the police were called.

On Thursday, detectives from British Transport Police and West Midlands Police launched a joint investigation to help identify the offenders and witnesses to the incidents.

DCI Tony Fitzpatrick from British Transport Police, said: “This was a horrifying ordeal for this young girl and we have specially trained officers supporting her.

“It is now vitally important we investigate exactly what happened on Tuesday morning as well as identifying offenders for both of these awful incidents."

The first offender is described as an Asian man in his early 20s with light skin, brown eyes, a skinny build, and about 6ft. He was wearing a grey track suit top and bottoms and black trainers.

The second offender is described as an Asian man in his early 20s, 5ft 6ins to 5fit 7ins, of large build with a tight beard. He was wearing a blue jumper and black jeans.

DCI Fitzpatrick added: “Whilst this incident happened during the early morning and there may not have been many people around, I would be keen to speak with anyone who may have been in the area at the time.

"If you were passing by the station and saw two girls walking with an older man, then please get in touch immediately.

“Likewise, if you saw any suspicious vehicles close to Witton station close to 2am then please get in touch as soon as possible.”

The age of the girl was originally believed to be 15.
