Tyla Cole was with her father, Marcus, when the dog turned on her at a friend's house in Norwich on Sunday.

Mr Cole, 34, of Cromer, Norfolk, managed to pull the animal off his daughter - but not before she suffered injuries to her back and thigh.

Police said: "Clearly this is a tragic accident which has resulted in a young girl receiving some nasty injuries."

"This is now a civil matter. No criminal offences have been committed," the spokesperson added.

The dog has now been destroyed.
