Falfurrias, Texas ? Rapper Lil Wayne and 11 people traveling with him were briefly detained Friday night after U.S. Border Patrol officers found marijuana on two of his tour buses, authorities said.

Lil Wayne, whose real name is Dwayne Carter, and the others were questioned and released, according to U.S. Customs and Border Protection, and the case was referred to the Brooks County Sheriff’s Office.

A sheriff’s spokeswoman told The Associated Press that she could not comment.

The tour buses were stopped in Falfurrias, about 80 miles southwest of Corpus Christi, where the rapper is scheduled to perform Sunday night.

Lil Wayne played in Hidalgo on Thursday. A few minutes before the doors were to open for his show in Laredo on Friday, it was announced that the show was postponed. A marketing manager for the venue told the Corpus Christi Caller-Times that it would be rescheduled.
