( CNN ) -- Mexican authorities say they 've detained the father-in-law of one of the country 's most wanted drug lords . Police Tuesday morning detained Ines Coronel Barreras , 45 , on drug-related charges , officials told reporters . He is the father-in-law of Sinaloa cartel leader Joaquin `` El Chapo '' Guzman , authorities said . In January , the U.S. Department of the Treasury described Coronel as a `` key Sinaloa cartel operative . '' Weapons and packets of marijuana were seized in Tuesday 's operation , but no shots were fired , said Eduardo Sanchez Hernandez of Mexico 's interior ministry . Authorities said Coronel is the father of Guzman 's third wife , Emma Coronel Aispuro , whom he married in 2007 . Guzman 's nickname , which means `` shorty , '' matches his 5-foot-6-inch frame , though he has climbed to great heights in the drug business . The Sinaloa cartel is one of Mexico 's most powerful drug-trafficking operations , and Forbes has estimated Guzman 's net worth at $ 1 billion . U.S. authorities arrested a woman believed to be Guzman 's daughter in October . She was deported in December after she pleaded guilty in federal court to possession of a false visa . Coronel 's arrest is one of the most significant blows to organized crime in Mexico since President Enrique Pena Nieto took office in December . The high-profile arrest comes two days before U.S. President Barack Obama is scheduled to arrive in Mexico . CNNMexico.com contributed to this report .
