Before being appointed as the head of Bolivia's department for controlled substances, Cáceres was a leader in one of the coca-growers' unions.

Bolivia's interior minister, Roberto Ríos, said that while the lab - which was big enough to employ 10 people - was found on land owned by Cáceres, investigations were still under way to determine if he was the owner of the lab. 

Ríos added that Cáceres had been detained 500m from the lab at a nearby sand and gravel plant he owns.

I, uh….I got nuthin.
