Jose Guadalupe Rivas Gonzalez, who was captured by troops on an undisclosed day, was described as a top lieutenant of Jose Antonio Acosta Hernandez, the reputed leader of the notorious La Linia gang.
The Defense Ministry said in a written statement that Rivas was armed and in possession of 10 pounds of marijuana when he was picked up.
The arrest of Rivas may put Mexican authorities a step closer to Acosta, whom the El Paso (Texas) Times said Sunday was the most wanted man in Chihuahua and oversees one of the two violent gangs locked in a turf war over the border city of Juarez.
Acosta's right-hand man, Marco Antonio Guzman Zuniga, also known sometimes as "El Brad Pitt," was nabbed in Chihuahua City last week, the newspaper said.
