Chief Keef has been arrested… yet again.

According to TMZ, the Chicago rapper was busted at an airport in South Dakota after authorities discovered weed and paraphernalia on him.

Airport police found four blunts and an edible in his backpack. He was in possession of more than an ounce of weed, so he was arrested and booked for possession of marijuana and paraphernalia.

Sources tell TMZ Chief Keef simply forgot he had it on him before boarding his flight.

He was in town for a performance in Sioux Falls.

The arrest comes just two months after Keef was arrested on a DUI charge in Miami.
