Colleton County sheriff's officials said a 17-year-old pointed his gun at a deputy before the deputy shot him.
The deputy, who the Sheriff's Office would not identify, tried to pull over a vehicle at 2:16 a.m. Sunday for an improper turn, according to authorities.
But the driver didn't stop, so the deputy chased the car, officials said. The suspect also tried to ram a different patrol car, according to an incident report.
The suspect stopped the car at a home off of Beachwood Road, where the suspect, later identified as Kareem T. Risher, of Smoaks, got out of the vehicle and ran, sheriff's officials said.
Risher was seen holding a handgun while he ran, deputies said.
While running from the deputy, Risher turned his upper body and pointed a gun at the deputy, officials said.
The deputy shot Risher three times in the buttocks area, according to investigators. He was taken to Medical University Hospital for treatment, officials said.
The State Law Enforcement Division is investigating the shooting, as it does every shooting involving a law enforcement officer.
The deputy was placed on administrative leave while the case is pending.
Colleton County sheriff's Lt. Amye Stivender said the deputy's name would not be released because of threats made and safety issues.
Stivender directed any additional questions to SLED, whose representatives were not available Monday for comment.
After Risher is released from the hospital, he will be charged with pointing and presenting a firearm, failure to stop for blue lights, unlawful carrying of a firearm, aggravated assault and other traffic offenses, according to officials. A similar shooting occurred in North Charleston on March 25, 2012, when a North Charleston police officer shot Carlton Pringle, who was 17 at the time. An officer shot Pringle once in the back, once in the buttocks and three times around the pelvic area, authorities said.
Officers had been responding to a call about shots being fired in the Ferndale area, officials said.
Police said that when the officer caught up with the Pringle, he turned and pointed a gun at the officer, who fired several shots, wounding Pringle.
