A FALSE alarm saw firefighters called to historic jewellers shop Prestons of Bolton after an employee accidentally set off a burglar alarm.

Crews were called to the Edwardian store in Deansgate at around 6pm yesterday after a ‘smoke cloak’ device was activated by a staff member walking down the stairs.

The security alarm lets off smoke to trap potential burglars and this triggered a call to the fire brigade about a potential blaze in the building.
