MEXICO CITY (AP) - Police in Mexico City say they have found two severed human heads on a street near the capital's main military base.
Mexico City Attorney General Miguel Mancera says the heads were accompanied by a note referring to the "Mano con Ojos" or "Hand with Eyes" drug gang.
It was the first multiple decapitation in the capital since January 2008, when two heads were found near the city's international airport. Two heads were found in the same vicinity in December 2007.
Decapitations have frequently been carried out by drug cartels in violence-plagued cities like Acapulco. But Mexico City has so far been spared much of the drug violence hitting other states.
The heads were found Monday on a busy ring road across from the army's headquarters at Military Camp 1.
