Neighbors discovered the grow operation in the 14200 block of 8 Mile between Greenfield and Coolidge when the back door to the facility was open.
The neighbor called police but before officers could arrive a man came by and shut the door. When officers arrived, it seems he wasn't interested in letting them in so they got a warrant to search the place.
The man claimed it was a licensed caregiver facility for medical marijuana but police say he's never applied to be a licensed caregiver and the property has never been licensed as a medical marijuana care center, so they are seizing all of the pot.
We're told one man was arrested and over 100 plants were seized from the building.
