After police received preliminary intelligence regarding the growing facility, officers were dispatched to stake out the site overnight Monday.

During the night, the officers spotted three men who came to work in the farm.

The three were arrested and the marijuana was confiscated.

Police said the plantation included some 12,000 plants.
