An investigation by the Council of Europe found the controversial "mosquito" device should be banned in Britain because it violates legislation prohibiting torture.

It found that "inflicting acoustic pain on young people and treating them as if they were unwanted birds or pests, is harmful [and] highly offensive".

The report also expressed concern its use could constitute a health hazard and lacked adequate medical research.

Britain has more devices in use than any other European state. It has been installed at more than 3500 sites across the country - compared with 5000 across Europe as a whole - since it first went on sale in January 2006.

It works by emitting a pulse at 16-18.5 kilohertz that switches on and off four times a second for up to 20 minutes. It emits an irritating, high-pitched sound that can be heard only by children and people into their early 20s, and is used to prevent teenagers congregating outside shops, schools and railway stations.

Critics, however, say the device targets all children and young people, including babies, regardless of whether they are misbehaving.

The council, which oversees the European Court of Human Rights, says the device contravenes international law prohibiting torture and inhuman and degrading treatment.

"It is neither politically acceptable nor consistent with the safeguard of fundamental human rights. For these reasons, legislative measures should be taken throughout Europe against the marketing of such devices and their use in public places should be banned."

Calls for a ban by Europe's oldest political body are likely to be approved by the council's parliamentary assembly in Strasbourg this week.

The report's authors revealed that although there had been co-operation with investigators from other countries where the mosquito is used, the British Government failed to respond to the council's questionnaire on the device.

The author's report, Polish senator Piotr Wach, said: "The lack of response from the UK, the country in which the 'mosquito' was developed, hindered the preparation of this report."

The mosquito is the brainchild of former British Aerospace engineer, Howard Stapleton, who came up with the device after his daughter was intimidated by a gang of boys hanging around outside shops.
