Young Thug -- Bails Out After Mall Cop Arrest

Young Thug is a free man after posting $10,000 bail Thursday afternoon following his arrest for threatening to shoot a mall cop.

Thug was picked up Wednesday by U.S. Marshals, who then tacked on charges of felony cocaine possession, felony marijuana possession, and three counts felony gun possession after raiding his home on Thursday.

Young Thug might have bigger problems ... he's been tied to the April shooting of Lil Wayne's tour bus.
