Police are appealing for information after a woman was raped in Manchester city centre in the early hours of Sunday morning.
Officers were called to reports that a woman was being raped on Granby Road Manchester before two passers-by intervened and the offender ran away.
The 18-year-old victim, who was with her friend at the time, had been approached by two men on Chorlton Street before they then proceeded to walk with them to Granby Road, where the incident took place.
Further enquiries have established that the second woman, aged 18, was sexually assaulted by the other man.
Both of the offenders are described as black men who are believed to be in their 20s.
Detective Sergeant Clare Smith of GMP’s Serious Sexual Offences Unit said: “This incident has understandably left both women extremely distressed and we are providing them with support from specially trained officers.
“We are actively seeking potential witnesses to this disturbing incident and I would ask that anybody who has information to please come forward.
“This happened following a busy Saturday night in Manchester and it is possible that there could have been a number of people in the nearby area at the time that may hold key information.
“I know people will be concerned by this incident and there will be an increased police presence in the area to provide reassurance to the local community. If you have any concerns then I would encourage you to approach one of our officers on patrol.
“I would like to finish by paying tribute to the two men who spotted what was happening and quickly intervened. Thank you for what you did.”
