Federal authorities have detained a former police officer accused of leading the armed wing of the violent Juarez Cartel in northern Mexico, the government said.
Marco Antonio Guzman, who had several aliases including "El Brad Pitt", was captured on Wednesday in the US border state of Chihuahua along with two alleged accomplices, according to a federal police statement.
Guzman, 34, was brought to the Mexican capital and shown, handcuffed, to the news media.
Police said Guzman was involved in the June 15, 2010 car bomb explosion that killed a federal police officer and two civilians.
They also accuse him of being involved in drug-trafficking operations across Chihuahua. The state is one of the worst-affected areas of the drug war. It is the state of deadly Ciudad Juarez, where an estimated 3,100 people were killed in 2010 alone.
