The owner of the car, Delesia Rattray told the Daily Mail she was stunned to return to her car to find the window smashed in and a note from the police to call them.
She had taken her 10-year-old sister, who owns the doll, to visit their mother in the A&E department.
"When I rang they said they had thought the doll was a baby in the front seat. Someone had phoned them to say there was a baby in the car. Some nurses had come out and agreed that it was a baby.
"The doll does look a bit real, like a baby a few months old, but if you look at the hands, which weren't inside the blanket, and feet you can tell it isn't.
"I can understand why they broke into the car if they really thought there was a baby inside."Nurses..? Nurses couldn’t tell the thing wasn’t real!?
