Mexico City ( CNN ) -- Eight drug traffickers belonging to Mexican drug lord Joaquin `` El Chapo '' Guzman 's organization have been captured , including a man presumed to be Guzman 's relative and confidant , officials said Wednesday . Federal police captured Victor Manuel Felix , alias `` El Senor , '' who worked for the Sinaloa cartel and was the leader of one of its financial networks , anti-drug police chief Ramon Eduardo Pequeno said . Felix is believed to be Chapo 's `` consuegro '' -- a Spanish word for the father-in-law of one 's son or daughter . Felix and seven others were captured in what was called Operation Beehive . Some 500 kilos of cocaine and $ 500,000 were seized as a result of the arrests , which took place last Friday in the states of Jalisco and Quintana Roo , as well as in Mexico City , authorities said . Police from Mexico , Ecuador and Colombia worked jointly in the investigation that led to the arrests , Pequeno said . Guzman is one of Mexico 's most-wanted drug kingpins , and has made Forbes Magazine 's list of the world 's billionaires , with a net worth of about $ 1 billion . The Mexican federal police investigation revealed those arrested participated in international drug trafficking and organized crime , police said . The agency conducted undercover operations that led to the discovery of the details of the illegal activities in Ecuador and Mexico . In the Ecuadorian city of Guayaquil , the organization had a cell comprised of members from Colombia , Ecuador and Mexico , who used various houses to gather and store drugs before shipping them to Mexico and the United States , the federal police said . Acting on this information , Ecuadorian police seized about four tons of cocaine and arrested nine suspects in Ecuador .
Police arrested Victor Manuel Felix and three other members of the Felix gang . Felix is the brother - in - law of one of Joaquin Guzman 's associates . Guzman is one of the most - wanted criminals in Mexico .
