Suffolk County police suspect a man who wears a surgical mask is responsible for five armed robberies since February.
In each crime, the man has donned a surgical mask before he enters the stores, displays a gun and demands cash, police said.
The man struck again about 2 a.m. Saturday, police said, robbing the 7-Eleven store at 796 Broadway Ave. in Holbrook.
In each robbery, the cashier complied with the demand for cash and the man ran away. He hasn’t injured anyone, police said.
Police said the robber, described as about 6 feet tall, also struck:
- A 7-Eleven at 139 Sunrise Hwy. in East Patchogue twice — at 11:45 p.m. Feb. 17 and at 3:20 a.m. April 21.
- A Speedway at 80 Horseblock Rd. in Yaphank at 8:15 p.m. Feb. 25.
- A Valero at 151 Hospital Rd. in East Patchogue at 1:55 a.m. Tuesday.
