Columbia, SC (WLTX) - Two more people have been arrested as part of the ongoing investigation following the beating of a jail inmate.

Sheriff Leon Lott says 51-year-old Todd Andrew Hollins and 36-year-old Olympica Latoya Tuten have both been charged with obstruction of justice.

Lott says the two failed to report the assault and lied to investigators about the sequence of events pertaining to the beating.

Last month, 37-year-old Robin Smith was charged with assault and battery of an aggravated nature in connection with the injuring of an inmate. According to deputies, Smith stomped on the inmate, causing internal injuries. Previous Coverage: Jail Officers Place on Leave | Victim in Beating Had Severe Internal Injuries
