Katt Williams and Suge Knight -- Arrested for Stealing From Female Pap

Suge Knight and Katt Williams got busted today for allegedly snatching a camera from a female photographer in Beverly Hills.

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 TMZ obtained Suge's mug shot ... taken after he was nabbed in Las Vegas. They were booked for robbery.

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

We shot video of the alleged victim talking to cops right after the run-in.
