Detectives are continuing to appeal for information after the death of a man from Burnley.
They were called to an address on Harley Street in the town at about 3.20pm on Saturday, March 2 after Paul Inskip was found with serious injuries.
He was taken to hospital but died on Saturday (March 9)
A postmortem examination showed Mr Inskip, 55, from Burnley died from a head injury.
Police say they are still trying to understand how Mr Inskip came by this injury and an investigation is continuing.
They are now appealing specifically for anyone who saw or spoke to Paul on either Friday March 1 or on the morning of Saturday March 2 to get in touch. He may have appeared confused or disorientated.
They would also like to hear from any motorists with dashcam who may have been in the area during that time, specifically on Harley Street, Ainslie Street, Pink Street and Woodbine Road.
Detective Chief Inspector Tracey McMurdo, of the Force Major Investigation Team, said: “My thoughts remain with Mr Inskip’s loved ones at this time. While we still don’t know how Paul came by his injury, we are doing all we can to try and establish this so we can give them some answers.
“I would appeal to anyone who saw or spoke to Paul on that Friday or Saturday to come and speak to us so we can try to piece together what happened to him.”
Three people have been arrested – a woman in her 40s and two men in their 30s – on suspicion of assault. They have been bailed pending further enquiries.
Anyone with information should contact police on 101 quoting log 0767 of March 2.
