The alleged incident went down back on Sept. 5 outside a studio according to the L.A. County D.A.

Katt was arrested this morning when he showed up in court for an assault case — and Suge was picked up in Las Vegas. They were booked for robbery.

Both men have pretty lengthy rap sheets and as a result the D.A.’s Office says Suge could face 30 years to life in state prison — while Katt could be nailed for up to 7 years.
