Police believe a burglary at a Sanctuary Cove jewellery store and three other break and enters may be linked.

Burglars forced their way into a store in a shopping complex on Masthead Way on Monday morning before smashing display cabinets and making away with jewellery.

Security staff disturbed the offenders before they fled in a silver four-wheel-drive.

They were seen heading west towards the Pacific Motorway.

Detectives are investigating possible links between this incident, three residential burglaries and five car break-ins at a Bayhill Crescent residential estate at Sanctuary Cove that occurred the same morning.
