Two youth are facing charges after Halifax Regional Police arrested three males in relation to two robberies during the overnight hours in Dartmouth.

Police say the first incident took place at about 11:45 p.m. Tuesday as three men, one armed with a sawed-off shotgun, walked into the Petro Canada at 610 Portland St. and demanded cash from the clerk. They left the store with cigarettes and an undisclosed amount of money.

Police say about 50 minutes later, three men — all wearing masks — entered Roberts Pizza at 364 Windmill Rd., with one armed with a sawed-off shotgun. They left with nothing, police say, and drove off in a gold coloured vehicle.

Police say about 20 minutes later, a gold Sebring was spotted by officers on Pleasant Street near Highway 111. Police say they tried to stop the vehicle, but the driver refused and drove to Novawood Court where all three occupants fled.

Police arrested a 15-year-old at the scene. K-9 officers then searched and arrested a 17-year-old male and 19-year-old man a short time later. Police say a shotgun was also recovered in a nearby field.

The 15-year-old and 17-year-old have each been charged with robbery, wearing a disguise, fleeing police and firearm offences. The 19-year-old was released, with the investigation on-going.
