A drone dropped a package of drugs into a prison yard while inmates were outside, sparking a fight, prison officials said.
The package was dropped July 29 at the Mansfield Correctional Institution in Ohio. It contained almost a quarter of an ounce (7 grams) of heroin, over 2 ounces (57 grams) of marijuana and more than 5 ounces (140 grams) of tobacco, JoEllen Smith, a spokeswoman for the Department of Rehabilitation and Correction, told the Mansfield News Journal.
Smith said there have been other instances of drones breaching security and the agency is taking steps to increase awareness and improve drone detection.
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 thrown over a fence to the south recreation yard.
Two corrections officers called for assistance and ordered the inmates to stop fighting, according to the department. They used pepper spray to control the fight.
About 75 inmates in the north recreation yard and 130 on the south recreation yard were strip-searched, run through a cell sensor and checked by a clinic. The nine people involved in the fight were placed in solitary confinement. No staff members or inmates were injured, the department said.
Last year, the Mansfield post of the Ohio Highway Patrol increased efforts to watch and catch criminals who throw contraband over prison fences.
