The streets of downtown Mineola near the Nassau County executive offices were the setting of a made-for-TV gunfire Tuesday as the CBS television series "Person of Interest" filmed two scenes for an upcoming episode.

The production, which began at 9 a.m. and was scheduled to continue through midnight, was filming scenes in which actors portrayed uniformed Washington, D.C., law enforcement and plainclothes officers.

The show, now in its third season, revolves around a reclusive billionaire and a former CIA operative who use a supercomputer to prevent violent crimes before they occur.

In the first scene filmed Tuesday, passengers in a vehicle traveling on Franklin Avenue near 15th Street "fired" on a group of people walking toward the Theodore Roosevelt Executive Office building. The production then went inside the building. Later, when filming moved to the rear parking lot, actors portrayed a scene that included firing at a moving vehicle.

Local police were on hand to control traffic, and offices and homes in the area were notified of the scenes, Nassau police said.
