Prison guards disrupted a high-tech delivery of illicit drugs and cell phones after spotting a drone hovering over the compound.
Officials at Hewell Prison in Worcestershire, England, noticed the device flying a shipment of contraband in the middle of a Saturday afternoon.
According to The Sun, the craft was carrying a potent strain of cannabis called Black Mamba, as well as Spice, a so-called “zombie drug” which is rife in the British prison system.
Guards reportedly managed to intercept the drop, which was said to be part of a “well planned and executed” criminal smuggling regime.
An unnamed source told the newspaper: “What the criminals didn’t expect was such a rapid and coordinated reaction by the authorities. They must have thought it had been successful – and are no doubt gutted now.”
Although the authorities managed to block one raid, said to have been on April 1, it was a rare victory in the struggle by prisons to control a new wave of drone-powered smuggling.
The devices have been behind hundreds of successful, undetected drops, which have become a large part of the drugs epidemic in the UK prison system.
The Ministry of Justice last week announced a specialist unit to take down drone smugglers, in a bid to take control of the problem.
