The Mexican army says it has dealt a significant blow to the powerful Sinaloa drug cartel with the arrest of the cartel leader's security chief.
The army says special military forces seized computer files and other data when they detained Felipe Cabrera Sarabia.
But Chief Army spokesman Gen. Ricardo Trevillo offered few details about the hunt for cartel leader Joaquin "El Chapo" Guzman.
Trevillo told a news conference Monday that Cabrera was captured without a shot being fired Friday in the capital of Sinaloa state, headquarters of the cartel allegedly run by Guzman.
Cabrera's nickname is "The Engineer."
Guzman is considered to be Mexico's top drug lord and is one of the world's richest men. He has eluded authorities since his 2001 escape from prison in a laundry truck.
