That high-profile arrest was followed by the arrest of 11 Beltrán Leyva hit squad members in Mexico City, with police noting that the arrests were the first evidence that Sinaloa had expanded into the capital city. U.S. Ambassador to Mexico Tony Garza called the arrests a "significant victory" in the drug war. With Alfredo in custody, his brother Arturo Beltrán Leyva took over as the brothers' top commander, but he was killed in a shootout with Mexican marines the next year.
