There's the link, BBC does not report any previous victims.
The report states a person was attacked, police turned up and destroyed two dogs, as they probably should in these situations.
It does not state the breed of dogs, but based on images I have seen of the dogs and person, again the issue is clearly with the owner having dogs he hasn't trained properly or cannot control properly. He didn't even have suitable leads for the control of the dogs. If you cant control your dogs from attacking a person, you should not be able to have a dog.
Its the posters in here who never want to admit responsibility will constantly put blame on the dog and its breed, instead of the scummy owner who has not looked after or trained the dog correctly.
