A woman in her 20s had been raped near to The Printworks in Manchester City Centre in the early hours of Sunday morning
The woman left a bar in The Printworks to go home, heading towards the exit of Exchange Square.
As she was walking towards Exchange Square, she heard someone shout “Where you at?” before two men approached her.
She was then raped.
The men are both described as white, in their mid-30s and having Manchester accents.
The woman is receiving support from specially trained officers and enquiries into the incident, including examination of CCTV in the area, are ongoing.
Officers are encouraging anyone with information to get in touch.
Detective Sergeant Nicole Charlton of GMP’s Serious Sexual Offences Unit, said: “We’ve got a full team of officers working to get this woman answers, thanks to her courageous actions to raise the alarm.
“I cannot stress the severity of what has happened and how important it is that people who have information that can help us build a fuller picture, get in touch.
“Did you see two men matching the description in the area around that time? Did you see anything suspicious or anything that didn’t feel quite right?
“Even if you think the information you have is insignificant, please report it to us so we can make that assessment – you never know, that could be the piece of information we need.”
Anyone with information should contact police on 0161 856 1831 quoting reference number 418 of 28/01/18 or the independent charity Crimestoppers, anonymously, on 0800 555 111.
