( CNN ) -- A suspected leader of Mexico 's Gulf Cartel has been arrested near the U.S. border , a Mexican official said Sunday . Mario Armando Ramirez Trevino was captured Saturday in Reynosa , near Texas , said Eduardo Sanchez , the Mexican government 's security spokesman . Ramirez , also known as X-20 , was found with three guns , nine cell phones , and thousands of dollars and pesos in cash , the spokesman said . According to the U.S. State Department , Ramirez is a ranking member of the Gulf Cartel . It had offered a reward of up to $ 5 million for information leading to his arrest and conviction . The Gulf Cartel is one of Mexico 's major drug-trafficking organizations . It 's not as powerful as it once was . Last week , authorities said they captured two dozen suspected members of the cartel -- including two top lieutenants . In September , they arrested Jorge Eduardo Costilla Sanchez , the then-reputed boss of the powerful Gulf Cartel . Ramirez ' arrest is the second capture of a major cartel leader in just a few weeks . Authorities nabbed Zetas leader Miguel Angel Trevino Morales , one of Mexico 's most wanted drug lords , last month . His arrest was the most significant blow to drug trafficking in Mexico since President Enrique Pena Nieto took office in December . The Zetas started out as the enforcement arm of Mexico 's Gulf Cartel , but later split off and formed their own drug-trafficking organization . CNN 's Nick Parker , Catherine E. Shoichet and Ana Melgar contributed to this report .
