A DOG was pinned down and slashed in the face in a North-East park at the weekend.

The male lurcher, called Rolly, was attacked by youths after being let off its lead at about 8.15pm on Sunday, in North Lodge Park, Darlington.

Police hunting the youths yesterday warned other dog owners to keep a close eye on their pets.

PC Anna Jakubowiak, of Darlington police's neighbourhood beat unit, described it as an unusual and nasty attack.

"The dog was let off its lead and ran towards a group of youths in the park," she said. "He's apparently very friendly with teenagers as he lives with some.

"There was then a loud yelp and the dog came back injured.

"His face was slashed and so was his left paw and there was bruising to his right foot."

She said it appeared that the animal had been pinned down while he was cut.

PC Jakubowiak said the dog had been to the vet twice.

"It is very sad and we're warning other dog walkers to be careful. If anyone knows anything about it we want to hear from them."
