Lil Twist Arrested After Court No-Show in Massey Beating Case

Lil Twist -- Justin Bieber's ex-pal -- got locked up after failing to show his face for a hearing in his assault case ... TMZ has learned.

Twist's lawyer showed up in a downtown L.A. courthouse Thursday morning, but that wasn't good enough for the judge who immediately issued a bench warrant. Twist got wind of the warrant and headed to court in the afternoon.

When he arrived he was taken into custody, and booked for failure to appear.
