Security officials are investigating a major leak of detailed prison layouts amid fears they will be exploited by criminals to smuggle drugs and weapons into prisons or used to aid an escape.
Emergency security measures have been deployed at multiple jails across England and Wales after the blueprints were shared on the dark web over the past fortnight. The schematic plans are also understood to include the location of sensors and cameras.
Prison officials believe that organised crime groups are behind the leak in order to help them deliver drugs into prison yards and cells via drones, or even to facilitate an escape.
