When police arrived they found out that the man had a truck parked deep in woods. In the back of that truck he had a whole vodka production factory going on at fool scale with over 300 liters of ready made product waiting aside.
He tried to mask the truck with branches, probably so that it couldn’t be seen from air or from long range. He moved the truck from time to time across the forest so that not to stay in one place for long.
Here is his operation going on.
When police arrived the man was right in a middle of the process. Sort of Russian (Belarussian) Breaking Bad with moonshine instead of drugs.
