A yob-busting alarm using ultra high sound to drive teenage thugs from shopping centres has been hijacked to create inaudible classroom ringtones, it emerged today.

Techno-savvy school kids are getting away with using mobile phones in class through the creation of ringtones adults cannot hear.

British firm Mosquito Loitering Solutions has been praised by the police for its Mosquito device which was developed to stop teenage gangs hanging around outside shops.

Once installed on a building, it emits a high-pitched sound, like a constant insect buzzing, to drive the problem away.

It is highly effective because it cannot be heard by most people over the age of 20.

Howard Stapleton, Managing Director of Merthyr Tydfil-based Mosquito Loitering Solutions, said he was “amazed” by the children’s creativity.
