Charleston police are trying to determine how 20 marijuana plants ended up growing in a community garden near a downtown public housing complex.

Police were tipped off Monday that someone was growing the pot in a plot near 105 Logan St., in Robert Mills Manor, home to 222 families.

An officer spotted the plants in plain sight. They were 3 to 8 inches tall, according to a police report.

Police yanked the plants from the soil and placed them into evidence. Investigators are still looking for the green-thumb suspect behind the illicit garden, police spokesman Charles Francis said.

Don Cameron, president of Charleston Housing Authority, said one of the agency’s assistant managers spotted the marijuana plants and alerted police. The garden is an unofficial plot, and the plants didn’t appear to have been there long, he said.
