WASHINGTON – There has been another violent incident against a speed camera van in the D.C. area.

An Ellicott City man was arrested on Tuesday for repeatedly driving past a speed camera van and firing glass marbles with a sling shot.

Around 5 p.m. on Tuesday, the speed camera van operator, who is a civilian employee of the police department, was clocking driver speed near an elementary school on Tridelphia Road in Howard County. He heard something hit the side of the van and saw a gray minivan passing.

Soon after, the same minivan passed again and the operator saw the driver launch the marbles.

Shortly after the operator called police, Bruce Lawrence May, 50, was picked up and charged with second degree assault, destruction of property and reckless endangerment.

He posted $3,000 bond and was released, police say.

On June 13, an unknown object was thrown at a county speed camera van on Route 99 and broke the back window. The day before, rocks were thrown through the window of another speed camera van on Route 29. In that incident, the van operator was struck and some equipment was damaged.

Police are investigating to see if the incidents were related.
