BRAZEN thieves phoned their victim to tell him they had stolen his car.
The intruders had broken into the man's Huddersfield home, found his car keys and driven off in his vehicle.
They then phoned him up early in the morning to tell him they had his car after finding his business card inside.
He did not even know it was missing until then.
The theft was the latest in a spree of so-called Hanoi burglaries in Huddersfield, when burglars break into homes to steal car keys and then drive off in the victims' high- value vehicles.
Police have repeatedly warned people not to leave car keys on show on kitchen tables or work surfaces, but to hide them or take them upstairs at night.
The areas targeted recently include Birchencliffe and the top end of Birkby.
One of the stolen cars was found near St Helens in Cheshire.
A police spokesman said: "We have put out warning after warning about Hanoi burglaries - but they still happen.
"People still think it will never happen to them. But it does happen to someone."
