Charleston County Sheriff Al Cannon and two of his deputies fired shots at a vehicle that led them on a 100-mph chase into the rural part of the county, a spokesman confirmed.
An official initially said Cannon did not fire shots but Capt. Eric Watson said Cannon fired shots at the vehicle shortly before the car crashed on Steed Creek Road about 10:15 a.m.
Watson said Cannon initiated the chase on U.S. 17 near Six Mile Road about 10 a.m.
Authorities say speeds exceeded 100 mph during the chase.
The car crashed and the suspect, Timothy Shawn McManus, 31, was bitten and captured by a police dog. He was not otherwise injured, Watson said.
McManus is charged with failing to stop for blue lights, resisting arrest, driving under suspension more than first. Additional charges are pending.
Two deputies were involved in a minor collision when they stopped on the road near the crash scene. One vehicle hit the quarter panel of another cruiser, but both vehicles were still drivable.
State Law Enforcement Division investigators have been requested because shots were fired.
