The criminal had been wanted since 2008. The arrest took place in the community of Franco Tavera, municipality of Juventino Rosas.
"This has been a great step to recover peace in Guanajuato," city mayor Diego Rodriguez said.
Guanajuato is one of the most violent states in Mexico because of the war between the Santa Rosa de Lima and the New Generation Jalisco Cartel. The two networks are rivaling to control fuel theft and drug trafficking.
El Marro led criminal teams that were in charge of stealing cargo vehicles, stock trucks, and ATMs. It also committed kidnappings, extortion, and homicides.
