Suge Knight Arrested After Cops Find Weed [Mug Shot]

Suge Knight was arrested in Las Vegas yesterday after a traffic stop gone bad, TMZ has learned ... and to make things worse, cops say he was carrying weed on him at the time.

Law enforcement sources tell TMZ ... the former Death Row rap mogul was pulled over at 5:34 PM Wednesday for making an unsafe lane change in his sick black Bentley.

But when cops ran Suge's name in the system ... they noticed multiple warrants out for his arrest, stemming from minor traffic violations.

After a quick search, cops say they found a small amount of marijuana in Suge's possession.

Knight was eventually hauled to a nearby jail for processing. He was released a short time later.

And things could get WORSE for Knight ... as TMZ previously reported, Suge is currently on 3 years unsupervised probation for driving on a suspended license.
