Investigations
 
Police said the money belonged to a drug gang that smuggled chemicals used to make methamphetamine, a powerful stimulant.

   

The attorney general's office said the gang operated behind a pharmaceuticals front company which imported tonnes of the chemical pseudoephedrine, used in making methamphetamine, from India.

   

The raid was the result of an investigation opened in December when police seized 19.5 tonnes of pseudoephedrine in Mexico's Lazaro Cardenas port, the attorney general's office said.
