The U.S. government is offering a reward of up to $5 million for information leading to the arrest of alleged drug trafficker Fausto Isidro Meza Flores.
The FBI said in a statement that Meza Flores is the leader of a trafficking organization based in the western Mexican state of Sinaloa and was the right hand of cartel boss Alfredo Beltran Leyva before his 2008 arrest.
He is known to use the aliases "El Chapo Isidro", "Chapo Isidro" and "Chapito Isidro."
The U.S. government said the organization was responsible for smuggling heroin, methamphetamine, cocaine and marijuana into the United States. Meza Flores is under indictment in federal court in Washington.
Anyone with information can contact San Diego FBI or the nearest U.S. embassy or consulate.
