A dog owner has almost had his arm ripped off after being mauled by two of his American Bulldogs, according to locals.
The 47-year-old man screamed for help as bystanders sought to stop the ferocious attack by hitting the dogs with golf clubs and garden tools.
Two drivers even tried ramming the dogs in their cars as the animals gripped the victim's head in their mouths, dragging him along the ground.
One witness told news agency PA his arm was severed, while another said it was "almost ripped off".
When the pets eventually ran off, people in High Pittington, County Durham, were left in fear until one dog was shot dead by police and the other was captured.
The search operation involved the force helicopter and armed officers.
An ambulance crew took the owner to the Royal Victoria Infirmary, Newcastle, where he was receiving treatment for his serious but non-life threatening injuries.
The victim, believed to be a local bulldog breeder, was out walking the dogs when the attack took place at around 9.10pm on Sunday night. He has regularly been seen in the area walking up to seven bulldogs.
Witness Alison Metcalf said she heard shouting outside her home at around 9pm.
"I thought I heard somebody shout 'help me' but I couldn't be certain, then I heard my husband come flying in, he threw our own dog through the front door, and said 'there's a man on the ground'," she said.
"The dogs were just ripping him to bits and dragging him around.
"Luckily he's a big guy but if it had been child or someone of a smaller build, it's likely they would not have survived the attack."
She said she had heard fireworks before the attack and thought the dogs could have been "spooked".
Another witness said: "I've never seen something so vicious and brutal in my life.
"People were behind the dogs in a car beeping the horn constantly to try and scare the dogs away, while some other people were also hitting the dogs with garden tools and golf clubs, but no matter what the dogs would not stop.
"Eventually the dogs stopped and ran away, and while they were running one of them was hit by a car, several times I think, but it still continued to run away.
"Both dogs ended up missing and then that is when an ambulance and a police car arrived at the scene.
"Not too long after more police cars arrived and also a helicopter."
Durham Police said one bulldog was "humanely destroyed" in the Coronation Terrace area "a short time after".
The dog that was caught will be kept in kennels while a decision is made about its future.
Durham City Neighbourhood Inspector Dave Coxon said: "I can confirm that both dogs were quickly captured by police and it was necessary for reasons of public safety to humanely destroy one of the dogs.
"I understand this must have been a shocking incident for those witnessing it and I would like to thank those members of the public for their efforts in trying to assist the man."
Police are offering counselling to witnesses of the attack.
