( CNN ) -- Troops closed in on one of Mexico 's most wanted drug lords Wednesday , nabbing him at a seafood restaurant in a popular tourist destination . Members of the Mexican Army did n't fire a single shot when they captured Hector Beltran Leyva in San Miguel de Allende , Mexico , officials said . His arrest came after 11 months of investigation as intelligence officials traced his path , Tomas Zeron de Lucio , the director of criminal investigation for Mexico 's Attorney General 's Office , told reporters . Mexican authorities were offering a reward of more than $ 2 million for information leading to his capture . And the U.S. State Department 's Narcotics Rewards Program had been offering a reward of up to $ 5 million . Beltran Leyva , who led a cartel by the same name , had been living a discreet , low-profile life in Mexico 's Queretaro state , ditching fancy cars and other trappings of luxury to appear as a simple businessman , Zeron said . But in reality , Zeron said , Beltran Leyva was `` one of the main leaders of drug trafficking in Mexico '' and headed `` a large network of corruption and money laundering . '' He rose to power after Mexican marines killed his brother in a 2009 raid that the head of the DEA described as a `` crippling blow to one of the most violent cartels in the world . '' More on the Mexican drug war . Nicknames for the kingpin included `` The Engineer '' and `` The H. '' According to security experts , the cartel had regrouped after the dramatic 2009 operation and developed alliances with the Zetas and the Juarez Cartel . The State Department has said the cartel was responsible for transporting weapons and ammunition to Mexico from the United States , and trafficking in cocaine , marijuana , heroin and methamphetamine .
