All three members of the hip-hop group Migos face drug and weapon charges following their arrests after they left the stage at a weekend performance at Georgia Southern University, authorities said.

The group and its associates arrived for the Saturday night concert on the campus in two vans, Bulloch County sheriff's officials said in a statement to The Associated Press.

Members of a crime suppression team detected "a very potent smell" of marijuana coming from the two vehicles, sheriff's officials said in the statement.

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

"These discoveries were intensely concerning as the drugs and firearms had been brought to a university sponsored event where over a thousand students were congregated," sheriff's officials wrote in the statement sent by Bulloch County Chief Deputy Jared Akins.

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 24-year-old Quavious Marshall; 20-year-old Kirschnick Ball; and 23-year-old Kiari Cephus.

Phone calls and emails to the group's management team Monday morning were not immediately returned. It wasn't known early Monday whether they have attorneys.
