There was a surprise guest at the Mansfield Correctional Facility in Ohio recently, and it wasn’t exactly human.

A drone flying over the facility dropped a package of drugs into the prison yard. The package is said to have contained a quarter of an ounce of heroin, over 2 ounces of marijuana and more than 5 ounces of tobacco.

The container almost immediately sparked a fight among the inmates, who all wanted a piece of the precious cargo.

According to the department, video footage showed the drone over recreation yards immediately before a fight began. An investigation determined the drone dropped a package intended for an inmate on the north recreation yard, and it was then thrown over a fence to the south recreation yard. (US News)

JoEllen Smith, a spokeswoman for the Department of Rehabilitation and Correction said that there have been “other” attempts of drones trying to violate prison security, and that her agency is actively trying to increase awareness and prevent such breaches from happening in the future.

These things are really kinda scary.
