Apparently singer Omarion wasn't aware of a warrant when he was pulled over for running a stop sign on Friday night (July 18) in the San Fernando Valley.

According to TMZ,

The officer ran his license and found there was a warrant out for his arrest ... for failing to appear in court on an earlier traffic ticket. The singer was cuffed and taken to jail. Omarion -- the former lead singer of B2K -- is being held on $20,000 bail.
In a video by TMZ, Omarion is seeing walking a long distance, with his hands behind his back, insinuating he had hand cuffs on.
