无人机撞墙后跌落到高墙上的铁丝网上，被贝尔福德女王监狱的警卫发现。这是史上首次无人机偷运事件。 

 

Guards quickly removed the drone - a DJI Phantom² 2, which costs up to £900 - and found a package attached containing class A drugs, a knife, screwdriver³ and mobile phones. 

 

The incident was revealed after the drone crash-landed at the 500-capacity category B prison on March 6. 

 

Prison bosses around the UK are now on high alert for copycat schemes using the remote-controlled aircraft. 

 

A prison source, who asked not to be named, said: "This is the first time I have heard of a drone being used to get banned items into a prison. 

 

The drone used in the smuggling⁴ bid can stay up in the air for just under an hour and has a range of just over 2,600ft - meaning the person flying it can stay out of sight of the prison. 

 

Drone experts have said operators need a "high level of skill" to be able to fly drones with pinpoint⁵ accuracy. 

 

A Bedfordshire Police spokesman said nobody had been arrested in connection with the incident, but added: "We were called to reports that a small drone had been discovered alongside a package in netting above a perimeter⁶ wall at HMP Bedford at 11.30pm on March 6.

 

"Both the device and the contents of the package are currently being examined, and investigations⁷ are on-going to identify the offender⁸. We are working closely with the prison to investigate this incident."
