MEXICO CITY, Mexico --
The Mexican military says it has arrested a man who was carrying 1,000 doses of heroin along with cocaine, methamphetamines and a weapon on a federal highway. A Defense Department statement issued Saturday says military personnel stopped the suspect the previous day at an unannounced checkpoint outside Tuxpan, north of beach resorts in the Pacific coast state of Nayarit.
A United Nations anti-narcotics agency recently reported that production of highly pure heroin is rising in Mexico.
Much of it is intended for smuggling into the United States. The U.S. Justice Department says Mexican drug cartels more than doubled heroin production in 2009.
