A man has been seriously injured after being attacked by a dog belonging to a family member.
South Wales Police said it received reports of "an incident involving a man and a dog" at Blair Way in Aberavon, Neath Port Talbot, at about 07:00 BST on Monday.
A 24-year-old, who police said was a relative of the animal's owner, suffered serious injuries and was taken to hospital by ambulance.
The dog - believed to be a pit bull or Staffordshire bull terrier - was sedated and taken away from the scene and an investigation has been launched.
A neighbour told BBC Wales: "It was a pitbull-type dog they rescued from a drug house about seven months ago.
"I saw seven or eight police cars at least here. There were armed police here searching for the dog.
"My door was getting banged at 07:30, police wanted to check our back gardens. They told us to stay inside."
The neighbour, whose house backs on to the nearby field, which is part of St Joseph's Junior School, pointed to bloodstained marks on a fence and gate.
"I thought it might be the dog’s blood but the boy’s brother arrived and told me it was the boy's. He’s in a bad way," she said.
"They don’t live here, they were walking the dog in the field when it happened."
A second neighbour said: "I saw a police man with a gun walking past my window, searching for the dog."
