Legal concerns arise over sonic teenager repellent


A black box emitting a high pitched pulsing sound designed to deter loitering teenagers is being used in thousands of sites around Britain just a year after its launch, prompting warnings from civil liberties campaigners that it is a "sonic weapon" that could be illegal.

The Mosquito device, whose high-frequency shriek is audible only to those under around 25, has been bought by police, local councils, shops, and even private home owners, to tackle concerns over groups of young people congregating and causing disruption.

Less than 18 months after the device, produced by Wales-based firm Compound Security, went into production, 3,300 have been sold -- 70 percent of them in the UK.

So great has been demand that the company is now working on a more powerful, 50m-range model designed to be used in larger areas such as cemeteries and hazardous building sites and is drawing up plans for a higher volume hand grenade version requested by the US prison service to help tackle riots.

However, while some local authorities and police forces are highly enthusiastic about the Mosquito, civil liberties campaigners Liberty are raising concerns about both the machine's legality and its effectiveness in addressing antisocial behavior.

A survey by the organization has identified the device being used in every region of England except the north east. In the north west of England police have mounted it on a car to drive to trouble spots.

Liberty director Shami Chakrabarti said: "At worst, the Mosquito is a low-level sonic weapon; at best, a dog-whistle for kids. Either way it has no place in a civilized society that values its children and young people and seeks to imbue them with values of dignity and respect."

"Degrading young people instead of providing opportunities for them is a tragic option whose long-term effect is frightening to imagine."

Liberty argues that the device is inappropriate, partly because it is indiscriminate, causing discomfort to and potentially driving away all teenagers in an area rather than specifically targeting those who may be causing trouble.

Alex Gask, one of the campaign group's lawyers, said: "Our objection is that this device is clearly designed as a way of getting rid of young people as a problem and about seeing them as a problem rather than identifying specific behavior they are engaged in and getting rid of that."

Liberty suggests the device may fall foul of article eight of the European convention on human rights, conferring the right to a private life, or article 14 on the grounds that it is discriminatory on grounds of age. The organization also believes it may contravene environmental health legislation -- a suggestion dismissed by inventor Howard Stapleton on the ground that many devices, including cars, are louder.

However, Liberty cannot attempt to bring a legal case itself, and must wait until a young person seeks to pursue the issue through the courts.

Meanwhile, the government has refused to give a view on the device. Last November, home secretary John Reid -- responding to his Liberal Democrat opposite number, Nick Clegg -- said his department had not discussed the Mosquito with its manufacturers or with the police. He said local agencies were encouraged to "consider the full range of innovations ... to reduce crime" and were then free to decide on the "most appropriate interventions."
