Five burglaries at houses in Jordanstown and Whiteabbey overnight are believed to be linked, say police.
A white Seat Leon car which was stolen from a house at Hampton Court has yet to be recovered.
The burglaries occurred at Chamberlain Mews, Hedgelea Park, Lynda Avenue, Meadowlands and Hampton Court.
Police say two men aged in their early 20s, wearing dark clothing, may have been involved.
Attempts were made at each location to steal a car using keys taken from the house.
Inspector Patrick Mullan is appealing to anyone who noticed any suspicious activity in any of these areas or who has any information which could assist with their enquiries to contact officers in Newtownabbey on 101 quoting reference number 1409 07/03/19.
“Our investigation into these burglaries is at an early stage but I would like to remind all householders to ensure all doors and windows are locked when they are out of the house or when they are going to bed at night.
“Most burglaries are opportunistic and if a door is left unlocked it is an open invitation for the criminal. If you have a burglar alarm make sure it is serviced and working correctly and most importantly make sure it is switched on. For further crime prevention advice please contact your local PSNI station on 101,” he added.
Information can be provided to the independent charity Crimestoppers on 0800 555 111 which is 100% anonymous and gives people the power to speak up and stop crime.
