The body of a missing man has been found on a Bolton building site.
Police are now trying to trace the movements of 30-year-old Karl Englemark after he was discovered near to Bridgewater Avenue on Monday.
Initial enquiries into Mr Englemark's death indicated there were no suspicious circumstances and a file was passed to the coroner.
The findings of a Home Office post-mortem were unascertained however, so police have now reopened the investigation into his death.
Mr Englemark was reported missing from his home in North Manchester on Thursday 1 February.
On Friday 2 February, he checked into the Hilton Hotel on Deansgate around 5.30pm and left approximately 10.30pm that evening.
He was not seen again until his body was discovered on a building site in Bolton on Monday 5 February.
Officers investigating the death are trying to trace his movements to find out exactly what happened to him.
