Two major supermarkets were cordoned off by police after a man shocked shoppers by spraying urine on the food.
The raider entered Morrisons in Glevum Way, Gloucester at around 11.20am yesterday and fired a "foul-smelling substance" – thought to be urine – on meat, salad and fruit.
He fled the store and went to Tesco four miles away in Quedgeley, where he a
gain sprayed the fluid on produce.
A 42-year-old man from Gloucester was arrested at the Tesco store on suspicion of causing criminal damage and remains in custody. He is thought to be behind both incidents.
Police do not believe the substance poses a risk to public safety but the shops have been sealed off while Environmental Health officers inspect them.
Staff are waiting in canteens of both stores, which are shut, and witness statements have been taken from several witnesses.
A Gloucestershire police spokesman said: "It is alleged that a man was spraying a foul-smelling substance, thought to be urine, on the foodstuffs, including the salad bar, fruits and meat.
"The device he was using is described as a kind of tube. Clearly this is a very unusual incident. A man has been arrested and a full investigation is under way. We are appealing for any witnesses who have not already contacted us to come forward."
Officers say they have no clues about the motive
