Police have launched an investigation after a man was killed by his own XL bully dog in Lancashire. Officers were called to reports of a canine attacking someone inside a house in Accrington shortly before 9.30pm on Tuesday, Lancashire police said. David Daintree, 53, the owner of the dog who lived at the address on Ashley Court, was found dead at the scene. The dog, since confirmed to be the banned breed, was shot by armed police officers to stop it from injuring more people as it continued to pose “a significant threat of serious harm”, the force said. Specially trained officers are supporting Daintree’s family. Lancashire police supt Marie Jackson said: “This is a tragic incident which has sadly resulted in a man losing his life and my thoughts are with his loved ones at this time. “We will have extra officers out and about in the area carrying out inquiries and I would urge anyone with information or concerns to speak to them.” In February, it became illegal to own an American XL bully dog without a certificate of exemption in England and Wales. Similar legislation came into effect in Scotland at the beginning of August. In Northern Ireland, it became illegal to breed, sell, exchange, gift or abandon an XL Bully-type dog last month. Owners must also ensure their dog is muzzled and on a lead when in public places. From 31 December, it will become illegal to own an American XL bully without an exemption in Northern Ireland.
