The unemployed man from Lower Austria won more than £100,000 on the show last May.
But instead of going on a dream holiday or buying his own home, the 29-year-old allegedly decided to build on the small fortune by mass producing cannabis.
Together with his girlfriend the man, who has not been named for legal reasons, rented a property in the capital Vienna in which to grow the plants.
Police, who caught the Millionaire winner as he made a delivery to a customer, said he had managed to harvest at least ten batches worth around £68,000.
