Submission + - Britain to deploy "sonic gun" at Olympics (

skipkent writes: Britain's military will be armed with a sonic device that can be used as a high-volume loudspeaker or a non-lethal weapon to disperse crowds at this summer's Olympic Games in London, the defence ministry said on Friday.

The equipment, which can project a piercing sound over hundreds of metres causing physical pain, has been used during protests at the G20 summit in Pittsburgh in 2009 and against pirates operating off the Somali coast.

The Ministry of Defence said it expected to use it primarily in loudspeaker mode to communicate with boats it wants to stop on the River Thames.

Defence chiefs have already caused controversy by announcing plans to put surface-to-air missiles on the top of residential buildings near the Olympics site in east London.
