An Algerian-born chemist has been found guilty in a British court of contaminating food and wine by using his own urine and feces.

The court had heard man sprayed the mixture in the Air Balloon Pub, in Birdlip, near Cheltenham on 14 May, 2008.

He then moved on to the Waterstones bookstore in Cirencester, Tesco in Quedgley and Morrisons in Abbeydale.

The court also heard shoppers and staff in both stores saw the man with a black lap top computer with a vapor coming from the bag being sprayed on the shelves. He is likely to be deported.
