Prosecutors have dropped charges against a man who authorities say threatened Dakota Access Pipeline security guards with a drone.
KXMB News reports Myron Dewey had been set for trial Wednesday (July 12) on a charge of stalking.

Mr. Dewey was accused of using a drone to zoom in on security guards and take photos of their faces and license plates.

Supporters say he was there to document the actions of the security guards. Previously he had pleaded not guilty to a misdemeanor stalking charge.

A court document says he also live streamed drone footage to his Facebook page.

KX says the judge in the case ruled that evidence from the drone could not be used in the case.

Mr. Dewey, who created Facebook page, Digital Smoke Signals, wrote that officers stopped his truck on County Road 83 and took the Phantom 4 drone without a warrant or placing him under arrest.
