A North Charleston man and his accomplice who reportedly held up an Augusta bank Thursday morning led local law enforcement on a high-speed chase though Aiken County during their attempted getaway, according to officials. Clifton Porterfield, 31, of North Charleston, and Angela Gibson, 35, of Moncks Corner, were chased into Lexington County, where they were arrested and turned over to the FBI, said Capt. Troy Elwell, a spokesman for the Aiken County Sheriff's Office. About 11:30 a.m., local deputies were notified that a bank robber had held up a Washington Road SunTrust Bank in Augusta and was last spotted on I-20 headed into Aiken County. "We got a call from an FBI agent behind the suspect vehicle," Elwell said. A deputy who went to assist with the chase spotted the vehicle, a white Chevy S-10 pickup truck, at mile marker 26 and began the pursuit, reaching speeds of 95 mph, Elwell said. As the deputy approached mile marker 36, nearing the Aiken/Lexington county line, he attempted to initiated a stop, but the vehicle would not pull over, Elwell said. When they got into Lexington County, the Lexington County Sheriff's Office joined the chase. At mile marker 55, Lexington County deputies deployed stop sticks, a tire deflation device. The vehicle hit the sticks and then slowed. The driver, later identified as Gibson, turned on a turn signal and pulled on to the shoulder. The two occupants put their hands outside the windows and were arrested. The vehicle and both suspects were turned over to the FBI. A pistol, ski mask and money were observed on the passenger seat and floorboard. Porterfield and Gibson have been returned to Richmond County and face a charge of robbery by intimidation. According to Augusta media outlets, Porterfield entered the bank while armed but never presented the weapon. He asked a teller to open an account for him before the holdup and gave him his ID.
