A post-mortem examination into the death of a Stone Roses fan found in a canal has proved inconclusive.
Christopher Brahney, 22, from Timperley, had not been seen since the end of the reunion concert at Heaton Park, Manchester, on Friday June 29.
His body was discovered in the Manchester Ship Canal near Media City in Salford Quays on Monday morning.
Last week The Stone Roses issued a statement through Greater Manchester Police asking for help with the appeal and said their thoughts were with Mr Brahney's family.
Police are now appealing for information to piece together his final movements.
From previous inquiries, officers believe that after the concert Mr Brahney used the park and ride facility at Bowlee Park, Heywood Old Road, towards Middleton. He could have been at Bowlee Park shortly before midnight.
Further inquiries also revealed that he may have been seen outside the Maccabi Sports Centre on Bury Old Road at about 12.05am on Saturday June 30.
Officers now believe that Mr Brahney managed to get into Manchester city centre in the early hours of June 30 where he picked up shoes that he had bought earlier that day and hid in Rosenfields car park on Thorniley Brow near to Shudehill Metro link station.
He also had sunglasses on his head.
Detective Inspector Debbie Oakes said: "Officers are continuing to offer support to Christopher's family, and we are trying to give them the answers they so desperately need.
"The post-mortem examination brought an inconclusive result, but, as is routine, samples have been sent for toxicology tests.
"We do however have a number of lines of inquiry that we are vigorously pursuing including CCTV footage that could help us make more sense of Chris's final movements, information from witnesses following the fantastic public response and other avenues for us to pursue.
"We understand that Chris walked from Shudehill past a number of pubs to Deansgate.
"Anyone who saw Chris in Manchester city centre, carrying a Primark bag, is urged to call the police as soon as possible."
Anyone with information should call police on 0161 856 7652.
