Police are today probing why a car described as playing "pinball" on the pavement rammed into a busy Glasgow bakery.

Three women had to be treated in hospital after the Toyota Yaris reversed into Greggs on Cambridge Street at 9am this morning.

Witnesses shouted warnings of "get down" and "get out of the way" just before the silver car ploughed into the shop, while another said the car looked like it was playing "pinball".

The three women are not thought to have serious injuries but are being treated at the Glasgow Royal Infirmary. The 56-year-old driver of the car was not injured.

Another witness reported how the vehicle had reversed into a woman on the pavement, shattering a window of the neighbouring former Littlewoods store.

The car then went forward, then reversed again into the Greggs store front, showering the pavement with glass.

Margaret McClair, from Hamilton, was dropping her daughter off for work when she heard a bang and saw the car "on top of a woman".

The 57-year-old said: "I heard a bang and my daughter turned around and the car was on top of the woman. The woman was half way under the car. The car went flying forward and everyone was running like mad. There were quite a few people in the shop and they all seemed to scatter."

One injured woman was treated on the pavement while the driver of the vehicle was being comforted by a member of staff from Greggs.

Andy Smeall, 24, from Airdrie, said he looked out from a nearby building when he heard a noise.

He said: "The car reversed in a half circle straight through Greggs.

"There was a woman in Greggs screaming like mad."

Another man, who didn't give his name, was in Greggs when the car hit and still had blood on his clothes.

He said: "I think it's someone else's blood. The place was packed - someone just said get down. I don't know what happened."

Four police vehicles, five ambulances and two fire engines attended the scene and a dozen officers interviewed witnesses while the street was sealed off.

A spokeswoman for Strathclyde Police said: "Three people were taken to Glasgow Royal Infirmary. Their condition is not thought to be serious. Inquiries are ongoing."
