Lil Pump was arrested in Miami on Wednesday (Aug. 29) for driving without a valid license.

Witnesses tell TMZ that the 18-year-old rapper was pulled over while driving a black Rolls-Royce. He is reportedly still in custody and his bond has been set at $500.

Officers initiated the stop after discovering that the license plate on the Rolls-Royce actually belonged to a Mini Cooper. When cops asked Pump for a driver’s license, he allegedly said he didn’t have one.

Earlier this year, Pump was arrested for firing a weapon in his home. He was taken to a juvenile detention center because he was 17 at the time.

The arrest comes as Pump is gearing up to release his new album Harverd Dropout and embark on his “Harverd Dropout Tour,” starting Sept. 28 in Denver.
