The man accused of leading police on a chase that resulted in three crashed cars and injuries to a pregnant woman and her 9-year-old is facing new federal charges this week.

Cleo Williams Jr., 24, of North Charleston is scheduled to appear in federal court in Charleston on Thursday morning to be arraigned for an additional count in connection with his September arrest.

Williams, who also faces state charges, was indicted in federal court for a weapons charge. In December, Williams was hit with two more weapons charges. On Feb. 12, Williams was indicted on a fourth count, a drug charge, according to federal records.

Starting in January 2009, Williams possessed cocaine with intent to distribute it and distributed cocaine, according to the superseding indictment.

On Sept. 6, police tried to stop Williams on Rivers Avenue near Greenridge Road as part of a drug probe across several jurisdictions, officials with North Charleston Police Department have said.

Williams sped up and police chased Williams, who then crashed into three cars on Rivers Avenue near Otranto, according to police. A 27-year-old pregnant woman and her 9-year-old were hospitalized for minor injuries. Someone in another vehicle that was hit also was hospitalized, police said.

Williams also was charged by the North Charleston Police Department with failure to stop for blue lights, unlawful carrying of a pistol, and assault and battery. Those charges also remain pending. Williams is detained at the Sheriff Al Cannon Detention Center in Charleston County.
