POLICE have relaunched their investigation over the body of a man found on a Bolton building site.
Officers are now appealing for help in tracing the last movements of Karl Englemark whose body was found at Cutacre earlier this month.
The 30-year-old had been reported missing from his home in North Manchester on Thursday, February 1 before his body was found on land near Bridgewater Avenue on the Logistics North site in Over Hulton.
The discovery of the body led to a large-scale police presence being deployed to the area, with a tactical aid unit vehicle, a crime scene investigation van and two police cars. A police helicopter was also scrambled, together with forensics officers.
Now officers say investigations have revealed that Mr Englemark checked into the Hilton Hotel in Deansgate, Manchester, at around 5.30pm on Friday, February 2.
He checked out at approximately 10.30pm and was not seen again until his body was discovered on the building site near Bridgewater Avenue shortly after 9.30am on Monday, February 5. 
Police officers originally found no suspicious circumstances relating to the death, but, after a Home Office post-mortem examination failed to determine the cause of death, the investigation has now been relaunched.
Police are now trying to trace Mr Englemark’s movements to find out exactly what happened to him.
Detective Inspector Steph Parker of GMP’s Bolton borough, said: “Sadly, Karl’s family do not yet know the events that led to his death, which is something we are hoping to find out for them. 
“We need to know how and why Karl travelled to Bolton, so we’re trying to track his movements between February 2 and February 5 and I’m asking the public to help me do this. 
“We know that Karl may have been chatting to members of the public on his travels, so I want people to really study the image we’ve released of him and get in touch with us if you remember speaking to him.
“What you spoke about could help us find out what happened to him. 
“Whatever information you have, please let us know so we can give his family the answers they deserve.”
