A Jacksonville rapper with a rap sheet is behind bars in Miami without bond after federal agents bust him in his hotel room.
Nehemiah Harden - who goes by the name SpotemGottem - is charged with aggravated assault with a firearm, possession of a firearm by a convicted felon and accessory after the fact to a felony.
Marshals allegedly found him in bed with an AK-47 next to him.
The 19-year-old was scheduled to perform at next week's Rolling Loud music festival.
