Teodoro "El Teo" Garcia Simental, one of Mexico's most wanted drug traffickers, was arrested Tuesday, Mexican and U.S. authorities.

Mexican federal police, assisted by the U.S. Drug Enforcement Administration, made the arrest in the city of La Paz, Mexico. Garcia Simental is accused of more than 300 murders, and disposing of them in acid -- most of them since he split from the Tijuana-based Arellano-Felix organization in April 2008.

There was a reward of up to 30 million pesos (U.S. $2.4 million) for Garcia Simental's capture.
