A member of the rap group Migos — already jailed after a concert at Georgia Southern University — has been charged with an additional felony after a fight with an inmate, police said Tuesday.

Kiari Kendrell Cephus, 23, of Lawrenceville, was charged with battery and causing a riot in a penal institution after a fight Saturday in the Bulloch County jail, according to Chief Deputy Jared Akins with the sheriff’s office.

Cephus, known by the stage name “Offset,” was involved with a fight with an unnamed inmate Saturday afternoon, Akins said. The alleged assault, which left an inmate with visible injuries, was captured by video cameras inside the jail, Akins said.

Cephus has been in jail since April 19, when he and other Migos members were arrested on drug and weapon charges after a weekend concert. The group and its associates arrived on campus in two vans, and that's when members of a crime suppression team made up of Statesboro police and sheriff's deputies detected "a very potent smell" of marijuana coming from the two vehicles, the sheriff's office said in a statement.

As the musicians went inside Hanner Fieldhouse to perform, investigators contacted the drivers of both vehicles. A search of the vans found multiple guns, marijuana and another undisclosed drug, the sheriff’s office said.

The three band members were arrested after leaving the stage and face charges of drug possession; possession of firearms in a school safety zone; and possession of firearms during the commission of a crime, sheriff’s officials said.

The musicians were identified as Quavious Marshall, 24, of Lawrenceville; Kirschnick Ball, 20, of Lawrenceville; and Cephus.

Marshall and Ball were later released on $10,000 bond, jail records showed.
