Four sheep killed in Staffordshire bull terrier attack
Four sheep have died and another 15 were injured after being savaged by a dog at a farm in Angus.
The dog, thought to be a Staffordshire bull terrier, attacked the sheep in a field at Newbarns Farm, Inverkeillor, at 12:30 on Tuesday.
Tayside Police said a passer-by had apparently restrained the "powerful" dog before the farmer arrived.
The farmer took possession of the bull terrier, whose owners are not known, and later handed it to police.
Officers said they wanted to trace the dog's owners and a group of people who were in the area at the time.
The animal was described as being large and powerful, and dark brown in colour.
Anyone with information about the dog or the attack on the sheep is asked to contact police.
