COLUMBIA, S.C. - A former state trooper who resigned last month after he was charged with assaulting two men during a traffic stop faces a similar charge, a State Law Enforcement Division spokeswoman said.

The March incident brings a new charge of assault and battery of a high and aggravated nature for former Lance Cpl. Chad Williams, 28, of Orangeburg.

The Orangeburg County Grand Jury indictment says Williams struck Willie Lee Footman, causing him "violent injury" during a traffic stop on March 14. SLED spokeswoman Kathryn Richardson confirmed the additional charges Friday.

In August, Williams was charged with two counts of assault and battery of a high and aggravated nature after a SLED agent said he struck two handcuffed men during a traffic stop on July 20.

Williams was arrested after SLED agents reviewed a videotape of the traffic stop on U.S. 301 in Orangeburg County made by cameras inside two patrol cruisers.

On those tapes, Williams is seen pulling over a car with three people inside that was driven by Travis Johnson, according to a sworn statement by a SLED agent.

Williams ordered a passenger out of the car and the man dropped what appeared to be some cocaine and ran into the woods, according to the statement.

While Williams chased the passenger, but couldn't catch the man who fled. When he returned to the car, Williams then hit Johnson in the chest with his forearm and struck the other man with his fist before slapping him in the face several times, according to the statement.

The officer providing backup for the stop, senior Trooper R.V. Giddens, has been suspended without pay since Aug. 1, according to the Public Safety Department. He has not been charged, SLED said.
