Police are investigating whether a doorstep row led to the death of a 53-year-old man in Devon at the weekend.
A 45-year-old man was arrested on suspicion of manslaughter following the man's death in Barnstaple on Saturday afternoon.
Police were called to the Gorwell area of the North Devon town by the ambulance service at 1.15pm. It is believed a 53-year-old man collapsed outside his daughter's house in the cul-de-sac.
The 45-year-old man, who is local to the area, was questioned at Barnstaple police station.
Neighbours reported hearing screams and then saw a group of people standing around a man who was lying on the ground.
Heather Castle said she had been haunted by the screams she heard. She said: "I was sitting on my bed when I heard the screams from the road behind. I looked out of the window and saw a group of people.
"An ambulance car then arrived and they were trying to resuscitate him for ages, it didn't look good. I just feel terrible, I wanted to help, the screams echoed around, I feel haunted by it."
Another neighbour Katrina, who did not want to give her surname, was one of the people to call the ambulance.
She said: "I heard screams and went outside, I saw the group on the road up the slope but at first I thought it was a child who had been hurt.
"The people on the phone were asking me for his age so I was shouting up to them. They said he was 53 and he wasn't breathing.
"I don't know him but he was at his daughter's house. I heard some people say they had seen him fall and then collapse."
It is understood the 53-year-old, who has not been named by Devon and Cornwall Police, had earlier been helping to move items into the house in Concorde Drive.
Detectives are investigating whether a row between the two men, who are understood to have known each other, contributed to the death.
A post mortem examination was held at the weekend to establish cause of death. The conclusions have not been released.
Witnesses reported brown evidence bags being removed from the scene by police as well as a people carrier being towed away on a recovery vehicle.
Police are appealing for witnesses to the incident to call the non emergency number 101.
