Lexington County Sheriff James Metts said Tuesday that 51-year-old Curtis Maroney told the 39-year-old woman he would revoke her bond if she didn't obey his commands.
After five days, investigators say Maroney drove the woman to visit her children at her father's home and she called deputies.
Maroney is charged with blackmail and trafficking in persons. He remains in the Lexington County jail. Bond has not been set and it's not clear if he has an attorney.
Metts says the woman had been arrested for driving under the influence and spent 12 days in jail before Maroney posted her $16,000 bond.
