A high-speed chase tonight through North Charleston began when a man tried to run over a Dorchester County sheriff’s deputy at a gas station, authorities said.

The deputy was on foot at Ladson and Dorchester roads about 8:45 p.m. when a motorist drove at the deputy, sheriff’s office Maj. John Garrison said.

The vehicle was pursued on Dorchester Road and stopped on a sidewalk after a minor wreck at Dewey Road. An arrest was made, Garrison said.
