Authorities say Rapper Lil Wayne and 11 people with him have been briefly detained after US Border Patrol officers found marijuana on two of his tour buses. Lil Wayne, whose real name is Dwayne Carter, and the others were questioned and released Friday night. Their case was referred to the local sheriff's office. A sheriff's spokeswoman told The Associated Press that she could not comment. A drug dog initially detected narcotics on one of the buses, according to US Customs and Border Protection. Marijuana was found during secondary inspections, the agency says.
