An appeal has been made for people to lock their vehicles and homes after 13 unlocked cars were entered in housing estates in Kilmacrennan and Termon.
Property including small cash, a laptop and a satnav were stolen from the cars which were left unlocked.
It is believed a gang were involved in the thefts which took place at an estate in Termon and the Lennon View estate in Kilmacrennan.
Six unlocked cars were entered in Termon and seven of 21 cars in the Kilmacrennan estate were found unoloked. The thefts took place sometime between 6pm on Wednesday and Thursday morning.
Inspector Michael Harrison of Milford Garda Station said the gang went round housing estates checking parked cars to see if they were locked.
“We would appeal to people not to leave anything in vehicles and not to leave their vehicles unlocked. “These are opportunistic thieves and we would appeal to people not to give them the opportunity,” he said. “The message is that this can happen if you leave your property unprotected these thieves will take advantage of the situation,” he said.
Inspector Harrison appealed to anyone who saw anything suspicious in the Kilmacrennan and Termon areas on Wednesday evening and Thursday morning to contact Milford Garda Station.
