COLUMBIA — A New York man who was shown on video being repeatedly kicked in the head by a South Carolina state trooper has been hospitalized for mental health issues several times since the 2006 incident, the man's attorney said Wednesday.

Sergio Caridi, of Catskill, N.Y., filed a lawsuit earlier this month against the trooper and state authorities.

Caridi's lawyer, James McBratney, told The Associated Press his client has been hospitalized for treatment of psychological problems since his arrest following a highway chase in May 2006 and suffered "significant physical injuries."

Video from a trooper's dashboard camera showed Cpl. John B. Sawyer kicking Caridi in the head several times after Caridi led troopers and sheriff's deputies on a 30-mile chase on Interstate 95 in a dump truck.

In the lawsuit, filed July 18 in Florence County, Caridi accuses Sawyer of using "brutal and excessive force," violating his civil rights, negligence and emotional distress. Caridi also names the state Department of Public Safety in the lawsuit, accusing the agency of negligence in training and supervising Sawyer.

Hired as a trooper in May 2000, Sawyer was placed on administrative leave after the incident. He resigned several months later, becoming a deputy for the Marion County Sheriff's Department.
