Mr Griffiths described how he had been in a cafe with his children and heard a “commotion outside” with “horns blowing, people shouting and screaming”.
The former Welsh Guard feared there had been a terrorist attack or major incident, so ran out and saw a woman lying on the floor with a dog “dragging her around” by the head.
It was a “large, stocky, silver chocolatey” dog attacking Ms Begum in front of her children and, after its muzzle slipped off, Mr Griffiths feared things could escalate further out of control.
As he moved closer, the dog went for him, and he said he “moved out the way and the dog missed – but at that stage I realised just how potentially dangerous that task was”.
“[I] ran up there, grabbed the dog and tried to get the dog off her as best as I could,” he said.
“I was already in the middle of it, so I couldn’t let go of the dog. I kept hold and calmed it down again.”
He was also able to put the dog’s muzzle back on.
