The robbery spree began on Feb. 13 2013, police said. That's when the man walked into the New Museum Deli, located at 370 Columbus Ave., just before 11 p.m., pretending to buy something — but then pulled a gun, demanded money and fled, police said.
Nobody was hurt, according to the NYPD.
The alleged robber also hit the Dunkin Donuts at 243 Ninth Ave. on Feb. 18; the One Stop Convenience Store at 1490 First Ave. on March 8; and the News & Discount Convenience Store at 1198 First Ave. on March 11, police said.
Police described the suspect as standing approximately 5-feet-7-inches tall and weighing between 170 and 190 pounds. He was last seen sporting a blue denim jacket and grey hoodie, they said.
