Cafe owner Clarke Rothwell, who witnessed the attack, said he heard a “loud popping noise that sounded like a balloon burst – a loud balloon”.

“When I looked round there’s a man stood there in his 50s with a white baseball cap on and a jacket with a gun, an old fashioned looking gun in his hand,” he said.

“He shot this lady once and then he shot her again, he fell to the floor, leant over shot her once more in the face area.
