MOBILE phones and phone cards worth about £40,000 have been stolen by burglars.

The raiders broke into the Carphone Warehouse, Silver Street, Durham City, through the roof.

They subdued the alarm system and smashed their way into a storeroom before taking phones worth £35,000 and sim and pre-pay cards worth several thousand pounds.

The break-in happened between 11pm on Monday and the early hours of Tuesday.

Several makes and models were stolen, including leading names such as Nokia, Samsung and Motorola.

Sergeant Paul Hadden said: "This has all the hallmarks of a well organised job which has been planned in some detail."

Police believe the thieves made off towards Prebends Bridge, where a vehicle was waiting for them.
