A sheep was severely injured in an attack by an out-of-control dog at a popular walking spot on the outskirts of Norwich.

Around 300 sheep were grazing on the meadow at Caistor Roman Town, three miles south of Norwich, when the dog launched its attack, causing the herd to scatter. 

One of the animals could not get away in time and was "nearly ripped apart" by the dog, which was not on a lead.

Natalie Butler, director of the Norfolk Archaeological Trust which manages Caistor Town, said: "It's really very awful. 

"The sheep is still alive, but it doesn't look good, not just from the physical injuries but the trauma of being chased by a dog.

"Our shepherd is very upset that this has happened and he is very worried about the other sheep and whether they will recover from the trauma."
