A 40-year-old Island Park man was arrested for robbing an Oceanside convenience store at knifepoint on Thursday, Nassau County police said. 
Steven Conde drove his Oldsmobile to the Dairy Barn on Oceanside Road where he got out of the car, walked inside the store, pulled out a knife and demanded money at 1:46 p.m., police said.
After stealing an unknown amount of cash, Conde fled the scene, police said. He was apprehended a short while later in Rockville Centre.
Conde was charged with robbery and criminal possession of a weapon. He will be arraigned Friday at First District Court in Hempstead.
