Police have tested a potential anti riot device that could be used to quell disturbances by emitting a high powered “wall of light” at the subjects. Such is the intensity of the light, that those affected by it are immediately forced to look away. A police spokesman has described the equipment as effective due to the fact that “if you can’t see something, you can’t attack it”.

Tests are still being carried out to examine potential risks to the public, or side effects.
