Sonic device deployed in London during Olympics
The Ministry of Defence has confirmed a sonic device will be deployed in London during the Olympics.
The American-made Long Range Acoustic Device (LRAD) can be used to send verbal warnings over a long distance or emit a beam of pain-inducing tones.
The equipment was spotted fixed to a landing craft on the Thames at Westminster this week.
The manufacturer denies it is a weapon and the MoD said it would be used “primarily in the loud hailer mode”.
