BUNGLING would-be burglars were foiled by a security device as they tried to break in to a cash and carry business in Astley Bridge.

The criminals attempted to enter the H&H business in Newnham Street just before 3am today via the roof, smashing through ceiling tiles as they made their way inside.

But once they had got inside the building they triggered a security alarm and also set off a smoke cloak device.

When triggered, the device releases plumes of smoke into a building, covering any intruders and obscuring their vision.

The would-be burglars fled the scene without managing to steal any goods or cash from the business.

Police were called, along with the fire service, who were asked to confirm that the smoke had not been caused by a fire.

A spokesman for the police said: "Clearly the security device has done the trick as the intruders left without taking anything."

An investigation is still ongoing and anyone with information about this incident is asked to contact the police by dialing 101.
