Ex-con arrested in border agent's killing

(CNN) -- Mexican police have arrested a man in connection with the death of a U.S. border patrol agent last week, according to a statement issued by authorities in Mexico.

Jesus Navarro Montes was arrested Tuesday in the town of El Yaqui, said the statement from Mexico's attorney general.

"Initial investigations indicated that Jesus Navarro Montes left Mexicali, Baja California, heading for the United States in a Hummer SUV that is believed to have contained drugs," the statement said.

"That same day, Border Patrol stopped him; in trying to avoid the agents, Navarro Montes ran over one of them and fled into Mexican territory."

Luis Aguilar, 32, a U.S. Customs and Border Protection agent who was assigned to the Yuma, Arizona, station, died in the incident Saturday, U.S. authorities have said.

The incident occurred in the Imperial Sand Dunes Recreation Area near Andrade, California, near where the state lines of California and Arizona and the U.S.-Mexico border meet.

Homeland Security Secretary Michael Chertoff said Aguilar was attempting to stop two vehicles believed to have entered the country illegally and were trying to abscond back into Mexico when he was struck and killed.

Navarro Montes had previously been arrested and imprisoned for transporting 10 undocumented immigrants to the United States, Mexican authorities said. E-mail to a friend
