AMBULANCE crews are dealing with a suspected medical episode at a Mcdonald's branch in Thornbury. 

Emergency services were called out to the fast food chain at 4.52pm over reports of a young girl falling ill.

An onlooker told the Telegraph & Argus: “There’s three police cars and an ambulance and it looks like someone is being brought out of McDonalds on a stretcher. I think it’s a girl.

“There are loads of people crowding around.

“More police cars are arriving as I speak. It’s obviously something really serious that’s gone off.”
