Amazon isn’t the only enterprise with aspirations of drone delivery. Maryland State Police say they arrested two men who were planning to use a UAV to smuggle contraband into a state prison.

The two men were arrested outside the state prison in Crespatown, Md., after police saw their vehicle. Police already had them under surveillance for a potential drone job, and searched the car. They found a drone inside, potential contraband and a gun.

Baltimore Sun reporter Alison Knezevitch reports that the contraband was a brand of synthetic marijuana called K2 spice and CDs containing pornography.

Even before Saturday night, authorities were suspicious of the pair delivering contraband to a particular inmate. When they searched that inmate’s cell after Saturday’s arrest, they found contraband.

But police haven’t been able to determine whether that means the two suspects already made a successful drone drop. We’ve asked for more info and will update if it becomes available.
