Masked men broke into two separate Dunkin' Donuts in Nassau after hours Sunday and stole money - in one case by carting away a safe, police said.
The burglaries occurred within 40 minutes at two retail locations less than half a mile apart, Nassau police said.
The thieves, police said, got away with an undetermined amount of cash.
Police are asking anyone with information regarding the burglaries to call Crime Stoppers at 800-244-TIPS. All calls will remain anonymous.
