New footage shows a plastic bag tied to a drone flying into a UK prison before hovering near a window.
Two pieces of wood then stick out from a window in the prison to pull the bag inside.
The incident was filmed in Wansdworth Prison, near London, and shows how criminals are using the new technology for their gain.
The number of banned items smuggled into prisons in England and Wales have doubled in the past two years, the BBC reports, with drugs and cellphones on the top of the list.
Before drones, people would often throw things over the walls, which they still do. Other creative methods have also been employed.
“There are all sorts of methods to get things over a prison wall. We’ve had people putting drugs in dead birds and sending them over with tennis racquets,” said John Attard of the Prison Governors’ Association.
Items were most often delivered to the prison in the early hours, past midnight.
