Neighbours of a father-of-six Mick Moss tried desperately to revive him as he lay unconscious in the front room.
Mr Moss, 48, died after suffering injuries during an incident at the house in Canal Street at 9pm on Wednesday.
A post mortem examination has revealed that he died from his injuries. A formal identification has not yet taken place.
Forensic examinations and searches continue at the scene today.
Detectives are appealing for witnesses.
Mr Moss's next door neighbour, Michael Skinner, said he was alerted to the incident after hearing noises coming from the house.
The 33-year-old said: "I heard a rumbling from next door and though nothing of it.
"I went downstairs, grabbed my mobile and called the police.
"I ran outside and saw him lying on the floor unconscious in the front room. There were a few spots of blood around him. I didn't go in but other neighbours did and they were trying to revive him."
Paramedics arrived and tried to revive Mr Moss but he died from his injuries.
Yesterday, police conducted house-to-house inquiries along the street while forensic officers worked at the scene.
A large white tent was set up in front of the house.
A friend of the Moss family, who lives in Canal Street, said: "I knew them really well. I couldn't believe it when I heard it was him.
"He had been looking after an old man that lived in the house and who was disabled but he was taken to hospital last week.
"It's terrible thinking about it. It's awful."
David Tonge, 47, of Canal Street, said: "We saw the forensics teams going up over the doors and checking in all the alleyways.
"My son saw them bringing the body out."
Another neighbour, Daniella Bestwick, 21, of Mill Street, said: "It's shocking. You are trying to raise children in the area. "
