Police attended and discovered the body of a 47-year-old man, later identified as Christopher Moore, at the scene.
Mr Moore's death was initially treated as non-suspicious, but following further investigation and a Home Office post mortem, police found that the man had suffered a number of injuries. An exact cause of death, police say, has yet to be established.
A 38 year old man from Nelson was arrested on Monday, July 2 on suspicion of murder and is currently in custody.
Detectives are now appealing for information following the murder.
Detective Chief Inspector Andy Cribbin, of the Force Major Investigation Team, said: “The attack on Christopher Moore is sickening due to the number of significant injuries he has sustained and the manner in which they have been inflicted.
"I believe that he has been individually targeted due to his vulnerability and it is thought to be an isolated incident.
"A number of his injuries are older in age and likely to have been caused in the weeks leading up to his death.
"He sadly died at his home address and appears to have been attacked there on or about the June 18.”
“We have a dedicated team of detectives and staff working on this investigation. There will be extra police officers in the area over the coming days and anyone with concerns should approach an officer.
“I am asking that anybody who has any information about the murder of Christopher, or any events involving him in the weeks leading up to his death please contact us.
"I am satisfied that there are a number of people within the community who can help us find out exactly what has happened to Christopher and I would urge them to contact us.”
“We are supporting Christopher’s family at this difficult time.”
In a statement Mr Moore’s family said: “As a family we are devastated by Chris’ death and urge anyone with any information to come forward, no matter how difficult.”
