Charleston police say a historical marker commemorating a 1960 Civil Rights sit-in was damaged by a truck Monday, about a week after it was erected.

A witness told police a large box truck was leaving a parking spot in front of the S,H. Kress & Co. building at 281 King Street about 5:45 p.m. when it appeared to accidentally hit the sign, police spokesman Charles Francis said.

The truck left the scene. Francis said the cab of the box truck is yellow.

Anyone with information about the truck or the driver can contact Charleston police at 577-7434.
