Related: PHOTO GALLERY: Neighbors discover pot factory in northwest Detroit business 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. Copyright Green Rush 2017 Scripps Media, Inc. All rights reserved.
