A shoulder-mounted laser that emits a blinding wall of light capable of repelling rioters is to be trialled by police under preparations to prevent a repeat of this summer’s looting and arson.
The technology, developed by a former Royal Marine commando, temporarily impairs the vision of anyone who looks towards the source.
It has impressed a division of the Home Office which is testing a new range of devices because of the growing number of violent situations facing the police.
The developer, British-based Photonic Security Systems, hopes to offer the device to shipping companies to deter pirates. Similar devices have been used by ISAF troops in Afghanistan to protect convoys from insurgents.
