A woman was left bloodied and bruised after a vicious 'XL Bully' attack in Hatfield admitted she is "petrified to go outside" and may require surgery on her injuries.

Sophie Dollimore was walking her dog on Stockbreach Road at around 9.40pm on Wednesday, July 3, when an out of control dog that she believes is the banned XL Bully breed bit her on the leg.

She was left bruised and covered in blood after suffering puncture wounds to her leg, which may now require surgery.

"I was taken to Barnet Hospital, and when the doctor looked at my leg, he could put a cotton swap all the way through the main bite," Sophie told the Welwyn Hatfield Times.

"I am having to go Barnet fracture and orthopaedic clinic because of the injuries I have sustained, and I might need surgery."

Sophie admitted she is now "petrified to go outside", and called on Herts police, who have a report of the incident, to take action.

"I am petrified to go outside now because the police have not seized the dog and the owner can’t control the dog. I’m scared I’m going to get a bitten again," she said.

"I was very scared that night and I don’t feel safe.

"I feel let down by the police as they have not done anything to protect me or the public because they haven't seized this dangerous dog. It’s been nearly a month and that dog could bite someone again."

Herts police confirmed to this newspaper that they are investigating the incident, and are working to "establish the breed".
