El Salvador's police found 45 barrels of a precursor chemical used to produce methamphetamine, which they say was smuggled into the country disguised as cleaning product.
The store of phenyl ethyl acetate was discovered in a house in the west El Salvadoran coastal state of Usulutan, reports newspaper La Prensa Grafica.
Authorities arrested a man who they say trafficked the chemicals into the country, and kept them stored in the house. Police said that the drugs would be worth $91 million after processing.
Latin American drug gangs are increasingly moving into the production of crystal meth, a drug that is in growing demand in the U.S.
