It looks like more legal troubles could be on the horizon for rapper Lil Wayne who was detained by U.S. Border Patrol agents in Texas on Friday. According to reports, authorities discovered marijuana on two of Wayne's tour buses.

Agent Joe Trevino said the buses were en route to Laredo, Texas from a concert stop in Hidalgo when they were stopped. The pot was detected by a drug sniffing K-9 the agent added. 

Wayne was among a dozen people being held. They were later released. The case has now been referred to the Brooks County Sheriff's Office for further investigation.
