Lil Wayne was booked Wednesday in Yuma on three felony drug charges.
The 25-year-old rapper, whose real name is Dwayne Michael Carter Jr., was being held at the Yuma County Sheriff's jail, said Capt. Eben Bratcher.
Carter was taken for a video arraignment late Wednesday morning in a justice court in Wellton, 35 miles east of Yuma.
He faces charges of possession of dangerous drugs, narcotics and drug paraphernalia, authorities said.
Bratcher said Carter was arrested by Drug Enforcement Administration agents at a Border Patrol checkpoint 78 miles from Yuma. Two other men were arrested with him, Bratcher said.
Sheriff's Major Leon Wilmot said he didn't know if Wayne had an attorney.
Birdman and Lil Wayne won a viewers' choice award for their song "Stuntin' Like My Daddy" at Black Entertainment Television's 2007 Hip-Hop Awards.
