*Sean “Diddy” Combs ran afoul of LAPD this morning when he made an illegal u-turn in the middle of Sunset Blvd.

Law enforcement sources tell TMZ that the mogul was cited around 1:30 a.m. for the traffic violation.

Diddy was said to be “cooperative” when the L.A. County Sheriff’s deputy approached his 2009 Cadillac Escalade. He was ticketed and sent on his way.
