Mexican Federal Police discovered an air-conditioned farm for cultivation of genetically modified marijuana in the state of Jalisco.
The National Security Commission (CNS), said that during a security patrol on Sunday, officers found the marijuana farm, spread over three areas - two on 2,200 sq.m and a third one on around 1,800 sq.m.
The female plants were genetically modified for cloning. Around 7,000 marijuana plants of different sizes were found.
The police cordoned off the area, and arrested 25 people, including 22 Colombians and three Mexicans.
One Colombian among them was responsible for cloning and nurturing the plants.
Those arrested, who were handed over to the public prosecutor's office in Mexico City, sought consular assistance to which foreigners are entitled to in such cases.
