The S.C. Highway Patrol is investigating a two-vehicle wreck involving a Charleston County deputy on U.S. Highway 78, authorities said.

The wreck happened about 9:20 tonight in the area of 9919 U.S. 78, said sheriff’s Maj. Jim Brady. No injuries were reported in the incident, he said.

The deputy, whose name has not been released, was one of several in the area investigating a hit-and-run about 9 p.m.

That incident involved a pedestrian being hit by a vehicle. The pedestrian was transported to a hospital with non-life threatening injuries, Brady said.

The vehicle involved in the auto-pedestrian incident left the scene, Brady said, and no information is known about it or the driver involved.

That incident remains under investigation by the Charleston County Sheriff’s Office.
