In the northwestern state of Sinaloa, the Mexican army discover a huge subterranean methamphetamine drug laboratory.
Troops found the methamphetamine laboratory while on a routine patrol in the town of La Cruz de Elota.
Methamphetamine, which is more commonly known as crystal meth, is an highly addictive illegal stimulant frequently produced in amateur conditions.
Authorities said the underground factory, the second to be found in the state of Sinaloa within a month, was four metres deep and measured 100 square metres.
Inside, three giant drug-producing reactors were found as well as tools, special suits and diverse chemicals used to make crystal meth, although authorities did not reveal the quantity of the drug seized.
