Steven Percival: Bolton murder probe appeal after brain injury death
A murder investigation is under way after a man died more than two months after suffering a brain injury, police have said.
Steven Percival, 40, from Great Lever, Bolton, was admitted to hospital on 25 April and died on 5 July.
A 48-year-old man has been arrested on suspicion of murder and a 57-year-old woman held on suspicion of attempting to pervert the course of justice.
Greater Manchester Police (GMP) said the investigation was "complex".
The two suspects were arrested in July and have since been released on bail, the force added.
Detectives are now appealing for anyone with information to come forward.
They believe Mr Percival suffered the head injury about a week before he went to hospital.
He then completed several more hospital appointments before his death.
Det Sgt Nick Haigh said: "Today would have been Steven's 41st birthday, which is a day he could have been spending with his family who have been left absolutely devastated by their loss.
"I would like to urge anybody with information about Steven's injuries that they believe can assist us to please contact police."
