Humberside Police are investigating the murder of 80-year-old James Fish, known to friends and family as Eddie.
He was found dead at his bungalow on Grimsby Road, near the Waltham end of the road.
A 28-year-old woman known to Mr Fish was arrested earlier in the day in connection with his death.
She remains in police custody but has not been charged at the time of writing.
Crime scene investigators collected evidence from the house earlier on Monday, January 29.
Detective Chief Inspector Stewart Miller, the Senior Investigating Officer, said: “We believe this to have been an isolated incident, and there is no risk to the wider public.
“The woman we have arrested was known to Mr Fish.
“We have specialist officers in place to support Mr Fish’s family and our thoughts are with them at this very difficult time.”
