Nassau County police have identified a man in the robbery of a Merrick 7-Eleven after watching him assault the store’s clerk on video surveillance.

According to a news release, Rivera, whose last known address is Newton Boulevard in Freeport, took magazines and concealed them in his jacket. When the clerk confronted him, Rivera pushed the man to the floor, causing him to sustain a laceration to his nose, police said.

The release said Rivera “then fled in a black BMW” and the clerk was able to get the car’s license plate number.

That information, plus the video surveillance, led to the identification of Rivera, police said.

Anyone with more information can call Seventh Squad detectives at 516-573-6754.
