Hi-tech gloves hold the key to fighting knife crime in Scotland:
Seven pairs of the specially-designed gloves, costing about £200 a pair, will be tried out for a month in Strathclyde and central Scotland. The battery-operated gloves allow officers to scan an individual for weapons with the fingertips or the palms of the hands. If metal is found, the glove, which is made from stab-proof Kevlar, starts to vibrate at the wrist.
