THIEVES have ruined Christmas for a Shepley couple by stealing their prestige cars.
They broke into the victims' home on Knowle Park between midnight and 3.30am yesterday while they were asleep upstairs and found two sets of car keys.
In the integral garage they let themselves into a £37,000 silver Porsche Boxster and a red Mini Cooper worth £20,000 and drove away in both.
The Porsche - number WJ02 KKS - and the Mini - YG04 VEA - were both still missing today.
Police have repeatedly warned that burglars - stumped by ever-increasingly tough car immobilisers and alarm systems - now burgle homes to get at car keys.
These crimes are known in police circles as Hanoi burglaries.
Det Con Steve Shaw, of Huddersfield CID, said: "We would urge people to always hide their keys away or, preferably, take them upstairs with them when they go to bed at night."
Det Con Shaw said such thieves tended to target prestige and high-value vehicles.
Anyone who spots either of the cars should get in touch with the police immediately.
Also, anyone with information about the criminals should phone Pc Dave Robinson on 01484 436664.
