PITTSBORO — Chatham County sheriff’s deputies, working with a State Highway Patrol helicopter, spotted a 30-plant marijuana crop growing near the Wake County line and uprooted the plants and destroyed them, they said Tuesday.

Chief Deputy Gary Blankenship said in a statement that the marijuana plants were spotted last Thursday. They weighed a total of 65 pounds, he said.

Blankenship estimated the street value of the marijuana leaves from the plants would have been about $130,000.

No arrests were made.

Airborne troopers work with law enforcement agencies around the state to spot drug-growing areas during the spring, summer and fall.
