Authorities say that three men are responsible for at least six armed robberies in Brooklyn since April. Their M.O. appears to be two men entering and robbing a store while a third awaits in a black Ford Expedition. WABC 7 reports, "The robbers hit the Sarubia Grocery at 1266 East 37th twice, on April 6 and April 22"—getting money in the 4/22 robbery (a customer was also injured). They also robbed a grocery store at 6106 3rd Avenue in late April, and a man was shot in the shoulder. Most recently, on May 9, they robbed Blondie's Deli in Windsor Terrace. According to WCBS 2, "Two young men...jumped up on the counter and tried to open the cash register...The latest attempted robbery was thwarted however when the owner chased the suspects with a bat and a scuffle ensued. Investigators say one of the suspects returned with a gun but the men ran away without any cash." Police are asking people to contact CrimeStoppers (website or call 800-577-TIPS) with any information.
