A BMW rolled down a hill, smashed through a back yard and two fences, before plummeting 15ft into a river, and landing on its roof.
The black 1 Series 56 registered car was written off after the handbrake failed.
Shocked owner Aisha Bagdadi said she had only popped into her friend’s house, in Progress Avenue, Blackb-urn, for five minutes.
When she left the property, shortly after 6pm on Tuesday, her car had gone and was later found upside down in the Riv- er Blakewater. The 29-year-old mother-of-one said: “The car was parked up and I definitely put the handbrake on. It must have failed.
“When I came out of my friend’s house, there were loads of police and, for a minute, I thought the car had been stolen, or that my husb-and was playing a joke on me.
“There was all sorts going through my head. I asked someone if there was a car in the river. They said ‘yes’ and I knew it was my car.
