AN AMBULANCE window was broken after a mindless yob threw a block of concrete at it.

The lump of concrete smashed the side window of the ambulance, which was being driven down Bag Lane in Atherton on Wednesday at 10.15am, and hit the stretcher.

Luckily no one was injured as there was not a patient in the ambulance, which is owned by the privately-run Blue Light UK.

Managing director Simon Forster said: “It was nothing but mindless violence.

“The driver was just going along Bag Lane when this lump of concrete comes flying through the window.

“It is an expensive window as well. The company that makes that vehicle doesn’t make them anymore so we have had to get it specially made.”

Ambulance engineer Mike Wallace, who was driving the vehicle at the time originally thought he had hit the curb until he started to hear the glass falling in.

“It wasn’t expecting anything to happen so by the time I had come to a stop I could only see the back of him,” he said.

“I tried to run after him but I couldn’t catch him.

“You just don’t expect someone to do that to a vehicle that saves people’s lives.

“It would be different if he has to ever ring 999 because his family member is in trouble. I am sure he wouldn’t be throwing bricks at it then.

“I’ve heard about incidents like this before but never when a vehicle was moving. He wouldn’t have known if anyone was in the back or not.

“The block actually hit the stretcher so if there had been a patient there it would have hit them if not in the head than the upper body.”

Mr Wallace said the man was about five foot six inches and was wearing a light blue hooded which was slightly shiny and dark coloured trousers which looked like tracksuit bottoms.

Blue Light UK has reported the incident to the police who have asked any witnesses to call them on 101.

The ambulance has been fixed and is back in service.
