Federal police say one of the United States' most-wanted drug traffickers has been arrested at Mexico City's airport.

U.S. authorities offered a reward of up to $5 million for Luis Rodriguez Olivera, or "Whitey." Olivera and his brother Esteban are accused of smuggling tons of cocaine and methamphetamine into Europe and the U.S.

Luis Olivera was indicted in U.S. federal court in 2009 on cocaine-smuggling conspiracy and related charges. Federal police said in a statement that the 39-year-old, red-haired suspect was arrested Tuesday.

His gang was known as "The Blondies." Authorities say it formed temporary allegiances with bigger Mexican cartels, including the Sinaloa cartel, the Zetas and the Gulf Cartel.
