A PIT bull terrier had to be restrained by police, and was later put down, after it turned on its owner in a terrifying street attack.
The man was walking the dog along Hudson Street, Accrington, on Tuesday evening when the animal was startled and began to attack him.
Eyewitnesses said the dog went crazy and bit its owner's arm and leg as he attempted to restrain it.
One man who saw the incident said: "I heard some dogs which sounded like they were fighting and saw two people with big white dogs and a smaller dog nearby.
"Then I heard a girl scream and the dog had its mouth around the man's arm. Then it seemed to go out of control. It had him on the floor and bit his leg.
"Lots of people started gathering around but nobody knew what to do.
"Then somebody phoned the police and lots of police vehicles came into the street - Land Rovers, dog units, cars. They eventually got the dog under control and it was taken away by an emergency vet."
Police arrived at the scene to find the owner of the pit bull on the floor trying to get the animal, which was foaming at the mouth, under control.
They had to bind the dogs' legs using handcuffs and used a jacket to cover its head in a bid to try to calm it down.
Inspector Steve Haworth said: "The dog was foaming at the mouth and acting quite aggressively and dangerously. The man was lying on top of the dog in order to restrain it."
The man suffered minor cuts to his body during the incident but is not believed to have been seriously injured.
The dog was destroyed by vets.
