CENTRAL ISLIP - A Centereach man who filmed himself disabling red light cameras over the summer pleaded not guilty Tuesday to criminal tampering and obstruction of governmental administration.

As News 12 has reported, Stephen Ruth posted a video on his Facebook page in August that shows how to disable red light cameras.

In the video, Ruth moves red light cameras in Ronkonkoma with a pole so they can't record drivers.

He says the cameras are a scam.
