Four Riverhead men have been arrested in relation to armed robberies in Mastic and Shirley in recent weeks, Suffolk County police said.
One of the men is only being charged in one of the two incidents, Suffolk County police said.
Robert Singleton, 25, Justin Braunskill, 25 and Tyrone Booker, 21, all of Riverhead, are facing first-degree armed robbery charges for a 10 p.m. holdup at a Dunkin’ Donuts on William Floyd Bypass in Shirley on Feb. 24, police said.
Those three men are also facing charges in another armed robbery that happened March 20 in Mastic, police said.
That armed robbery occurred at a Valero gas station on Montauk Highway, and all three men, along with a fourth man, identified by police as Trayrone Booker, 19, of Riverhead, are facing second-degree robbery charges for that incident, police said.
All four suspects were arrested on Montgomery Avenue in Mastic on the night of the second robbery, police said.
In the first incident, at Dunkin’ Donuts, one of suspects produced a handgun, demanded money and the group fled the area, police said.
In the second incident at the Valero, the suspects also displayed a handgun and demanded money and cigarettes, police said.
All four men were arraigned in Suffolk County District court on different dates after March 20, according to online documents.
Workers at both locations declined to comment.
It also was not clear why the three suspects were charged with first-degree robbery — a class B felony punishable by up to 25 years in prison and a five-year mandatory minimum for someone with no criminal record — in the first alleged incident, and second-degree robbery in the second case.
Second-degree robbery, a class C felony according to NYS Penal Law, carries a 15-year maximum prison sentence if convicted.
