Officers are becoming increasingly concerned for the welfare of an Oldham man.
Calum Rogerson was last seen at 10.30pm on Monday 29 August 2016 at Bar Pop on Canal Street in Manchester city centre.
The 24-year-old has not been in contact since and it is thought he does not have a phone, money or bank cards on him.
He is white and described as 6ft 3ins, of muscular build, with short brown hair and brown eyes.
On the night he went missing he was wearing a white t-shirt with a large Armani logo on the front.
He was also wearing navy knee length Armani shorts, black Adidas trainers and a silver Hugo Boss watch.
Detective Constable Kelly Bragg, from GMP’s Oldham borough, said: “Calum, if you are reading this, your family are understandably extremely worried about you.
“Please could you get in touch with us or your loved ones to let everyone know you are safe and well.”
Anyone with any information about Calum’s whereabouts is urged to call police on 101.
