A major double manhunt has been launched after a sickening back-to-back assault in Birmingham, England.

Detectives said the teen was first attacked in a secluded part of Witton railway station, near the Aston Villa football ground, about 120 miles northwest of London, sometime between 7 p.m. Tuesday and 2 a.m. Wednesday.

The victim had walked to the station with her friend but was led away by a man who approached her.

Shortly after that attack, the girl walked out of the station and flagged down a passing vehicle to ask for help.

But after getting in the car, she was raped a second time by another man.

A major investigation, involving detectives from the British Transport Police and West Midlands Police, is under way to try to identify both attackers and appeal for witnesses.

The first attacker is described as Asian with light skin, brown eyes, a skinny build and about 6 feet tall. He was wearing a tracksuit top and bottoms, black trainers and was in his early 20s.

The second attacker is also described as Asian, in his early 20s, 5 feet 6 or 5 feet 7 inches tall, with a large build and a close-cropped beard and was wearing a blue shirt and black jeans.

Detective Chief Inspector Tony Fitzpatrick, of 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.

“My detectives are currently examining all available CCTV in an effort to identify the offenders and whilst these enquiries are made, we are keen to speak with any potential witnesses.

“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 2 a.m., then please get in touch as soon as possible.

“Your information could prove vital in our enquiries to identify the perpetrators.”

Fitzpatrick added: “We are now doing all we can to trace the people responsible and bring them to justice.”
