There was struggling going on - we could see him strangling the girl and she was trying to kick him and push him out.

Mr Berking tended to the woman - who was very upset and had obvious facial and neck bruising - while his friend Barrie Olsen, 36, followed the man.

He said the man ran towards the nearby Denny's restaurant.

"He tried to do a loop-de-loop around a van and ran back across the road towards the library where I was still on the phone. He ran straight towards me so I managed to kick his legs out from under him and he fell over and the rest of the boys piled on top of him.

"He was a big boy, but we have some big boys here, too."
