In 1987, a serious and unprecedented health warning was issued to Edinburgh shoppers as it emerged that a man had been spiking supermarket products with poison and glass.
A huge police operation was launched that June after the man targeted three Edinburgh Safeway stores in Cameron Toll, East Craigs and Davidson's Mains. One girl was left with cuts to her mouth due to shards of glass deposited in a tub of coleslaw, while the mystery poisoner also spiked grapefruit juice with weed-killer and laced yoghurt with arsenic.
A red label was on the tub of coleslaw, warning of the glass, while the juice also carried a similar warning.
