A fight broke out at an Ohio prison last week when a drone dropped a package of drugs onto an outdoor recreation yard, the Associated Press reports.

Officials say the aerial outlaw dumped almost a quarter ounce of heroin, over 2 ounces of marijuana and more than 5 ounces of tobacco over Mansfield Correctional Facility, igniting a brawl on July 29. From the Mansfield News Journal:

Upon reviewing the cameras, it was determined that a drone passed over the recreation yards immediately before the fight began. Further investigation revealed the drone dropped off a package intended for an inmate. The package was picked up on the north recreation yard, setting off a fight.

“Our agency’s top security administrators are taking a broad approach to increase awareness and detection of unmanned aerial systems,” a state correction agency spokesperson told The Columbia Dispatch.

According to the paper, authorities are still investigating who was operating the robotic bootlegger.
