Mancs criminal has been known to target jewellery reps on the road.
Police are on the hunt for a jewel thief who is believed to have followed and robbed jewellery reps by hiding sophisticated tracker devices on their cars.
Mark Cunniffe is accused of having stolen thousands of pounds-worth of diamonds in the London and Manchester areas and is currently wanted by police for conspiracy to steal £220,000 worth of diamonds in Prestwich in June last year.
In separate incidents, £150,000 of diamonds were stolen in Salford and police managed to intervene to prevent a third robbery when a rep for Gems of the World discovered that he was being tracked after taking his car to a mechanic.
50-year-old Cunniffe, who is from Ancoats in Manchester, is suspected to be part of a gang that is targeting the jewellery industry. The gang uses satellite trackers that it affixes to cars and then follows the reps. When an opportune moment arises, the gang approach the vehicle, smash the windows and steal any jewellery or loose stones inside.
