Young Thug Arrested After Threatening To Shoot Mall Cop

Young Thug was taken down by the U.S. Marshals Wednesday morning after allegedly threatening to kill a mall cop.

Law enforcement sources tell us, security at a Georgia mall asked Thug to leave ... it's unclear why. The guards were escorting the rapper out of the mall when he allegedly said he was going to shoot one of them in the face.

At that point the real cops were called.

Thug left before cops arrived and a warrant was issued for his arrest. The incident occurred last week, but it took until today for U.S. Marshals to track him down at a home outside the ATL and hook him up.
