A drone dropped drugs in a package near a Mansfield Correctional Institution recreation yard in Ohio, investigators say.

The package, which contained 6.6 grams of heroin, 65.4 grams of marijuana and 144 grams of tobacco, was dropped July 29 at about 2:30 p.m., according to Fox's Cleveland affiliate Fox 8.

Officials initially responded to a fight that broke out in the prison's north recreation yard. Other inmates from the north and south recreation yard began running to the fight. The inmates were all ordered to the ground, taken to the prison gyms and searched.

It wasn't until officials saw video footage of the drone dropping off the package into the north recreation yard that they realized what was going on, according to The Huffington Post.

An investigation determined that the package was intended for one inmate but had been discovered by another, who then threw it over the fence to the south yard which set off the fight.

After the inmates were cleared from the recreation yards, prison officials searched the yards and several other areas on prison grounds before finding the package in an equipment room.

Now, the State Highway Patrol is working to determine who flew the drone over the prison and for whom the package was intended, according to The Columbus Dispatch.

While it's not uncommon for drugs to be placed into tennis balls and then thrown over prison walls, using a drone to deliver the drugs instead is unprecedented.

It appears smuggling in prisons has gone high-tech.
