An energetic XL Bully dog who was recently adopted has mauled its owner at home before escaping to a nearby school car park, sparking panic as pupils were forced to evacuate.

The six stone dog, called Denver, attacked his owner in her back garden in Brisley, Norfolk, on Monday afternoon. The victim, in her 60s, could be heard screaming as police rushed to the house and helped free her from the vicious attack. 

But Denvor managed to flee and ran free through the streets before being found an hour later in the car park of Brisley Church of England Primary Academy. 

All pupils were rushed inside the building until the XL bully was tied to a post then the school was able to evacuate. 

Police said that with permission of the owner and in the interest of public safety, the dog – which the owner had adopted less than a month ago – was destroyed. 

The victim was meanwhile taken to Norfolk and Norwich University Hospital with multiple non life-threatening injuries. 

The latest in a spate of attacks by the breed comes one month after Prime Minister Rishi Sunak pledged to ban the American XL Bully by the end of the year.

After Monday’s incident, Headteacher Belinda Allen told the Eastern Daily Press: ‘Our school staff were alerted by the police that there was a dangerous dog and immediately actioned staff to clear the area.

‘There was no immediate danger to staff or children within the school area.’

Denvor was adopted from Dogs Trust Snetterton less than a month ago. He reportedly had ‘no history of aggression’ and it was believed that he had settled in well to his new home.

Ahead of his adoption, the trust shared a photo of a ‘smiling’ Denvor as he ran in a grassy field. The post read: ‘He’s full of beans and full of smiles as he’s been reserved!’

Dogs Trust will be ‘undertaking a thorough investigation’ into the attack, with a spokesperson telling The Dereham Times: ‘Our priority at this time is to provide as much support as possible to people affected by this incident.’

Police have described it as a ‘terribly sad and distressing situation’.

Inspector Diana Woodage said officers faced a difficult situation as they arrived to find the woman being ‘viciously’ attacked by her dog. She said the victim was very clearly injured and in pain.

Norfolk Police told MailOnline in a full statement: ‘A woman who was mauled by a XL Bully dog in Brisley yesterday (16 Oct) is recovering from her injuries.

‘Officers were called to Brisley shortly before 3pm yesterday after a member of the public called police to report that a woman was being attacked by an XL Bully dog in the back garden of her property in Gately Road and was screaming for help.

‘Officers arrived at the scene to find the victim – a woman aged in her 60s and the dog’s owner – being mauled by her pet XL bully dog. 

‘She received multiple injuries in the attack and was taken to the Norfolk and Norwich University Hospital for treatment. Her injuries were not life threatening.

‘The dog, which escaped from the property following the attack, was found by officers in School Road shortly after the incident. Someone had managed to secure it to a post in the car park of a local primary school. Pupils and teachers were still present and inside the main school building at the time.

‘Police contacted multiple veterinary practices for help to sedate the dog but none were able to attend. Due to the threat to the wider public, and with permission of the owners, the dog was destroyed.’

Insp Diana Woodage added: ‘This was a terribly sad and distressing situation. Officers were faced with an incredibly difficult situation when they arrived at the scene – a woman being viciously attacked by her dog and was very clearly injured and in some pain. 

‘In the interests of public safety and at the request of the owner, the dog was humanely destroyed.’

MailOnline has contacted Dogs Trust and Brisley Church of England Primary Academy for further comment.

In a video announcement posted to his X – formerly Twitter – account last month, the PM said the breed would be banned following a ‘pattern of behaviour [that] cannot go on’.

Mr Sunak said he has ordered ministers to convene a panel of experts, including the police, to define the breed so it can then be outlawed.

Just last week an out of control XL Bully dog bit a young girl in front of panicking teachers as it launched a vicious attack on a group of primary school children.

Eyewitness said the ‘huge’ and ‘out of control’ animal, which allegedly wasn’t on a lead, ‘latched onto’ a young girl as teachers desperately tried to pull her away.

Police are now trying to trace the animal and its owners following the incident.

The drama unfolded at Salford Quays, Manchester, shortly before 11 am on Thursday morning. 

A group of around 20 kids, said to be from a local primary school, who were accompanied by three teachers, were walking over the bridge that crosses the Mariner’s Canal from the area next to the Beefeater pub, over the Watersports Centre, when the incident happened. 

In yet another incident last week, an out-of-control XL Bully was ‘destroyed’ after a savage attack left a ‘mother and daughter’ in hospital.

Emergency crews were called to reports of a dog attack on Baker Crescent in Baddeley Green, Staffordshire, at around 11:40am on October 12.

Witnesses said there was also a police presence on nearby Brompton Drive. One resident said a ‘mother and daughter’ were injured in the attack.
