Suffolk County Third Precinct police officers responding to a robbery call at an East Islip 7-Eleven store early Friday located and arrested the teenage suspect not far from the scene, police said.
The suspect, identified as Maxwell Purdy, 19, of East Islip, was charged with first-degree robbery.
Police said Purdy entered the 7-Eleven at 2 East Main St. at about 2:20 a.m., displayed a knife, demanded cash and then stole cash and cigarettes before fleeing the store.
One of the responding officers, identified as Christopher Calderone, was able to locate Purdy on nearby Woodland Drive and take him into custody not long after the robbery occurred, police said.
Purdy was arraigned in First District Court in Central Islip later Friday. His bail, which was not immediately posted, was set at $50,000 bond or $25,000 cash, and a temporary order of protection was issued, according to online court records.
