A teenage girl has been raped twice in one night by two men in separate incidents.
The 15-year-old had asked her second attacker for help after the first attack.
The girl was with a friend at Witton train station when they were approached by a man who led her to a secluded area and raped her.
After the attack, the teen rushed away from the area and flagged down a passing car to ask for help.
But when she got into the vehicle she was attacked and raped for a second time by a man who is believed to be a repeat offender.
Both men are described as Asian men in their early 20’s.
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.”
