An unemployed chemist was jailed for nine years today for contaminating food and wine by spraying his own urine and faeces in supermarkets in Gloucestershire.
Algerian Sahnoun Daifallah also sprayed the slurry over children's books and in a pub as he carried out his foul campaign by concealing a 1.5 litre weed killer container in a lap top bag modified to allow the nozzle to poke out. And it was revealed that he intended to bring his campaign to Birmingham.
Daifallah, 42, was last month found guilty of four counts of contaminating goods at Tesco, Morrisons, Waterstones bookstore and a pub in Gloucestershire on May 14 and 16 last year. The incidents caused £700,000 of damage to products and in lost businesses when the stores had to close.
When police searched his house they found stockpiles of the mixture and plans to spread the muck in other cities including Bristol and Birmingham.
Daifallah, who had fantasies about biological weapons to cause public alarm, was also found guilty of having an offensive weapon, namely a catapult with marbles.
Judge Carol Hagen said security agencies had labelled Daifallah, who has a degree in industrial chemistry, a very high risk to public safety. She sentenced him on Tuesday at Bristol Crown Court to concurrent sentences of three years, five years and two of nine years for the contamination offences and 12 months for possession of a weapon.
She told him that during the seven day trial, in which he had represented himself, she found him to be "arrogant and inflexible" in his thinking.
She added that she had wanted to jail him indefinitely but the law would not allow her to.
"Your actions showed a callous disregard for public safety and you caused considerable alarm and anxiety," she said. "You caused substantial police and forensic involvement given that the nature of the substances were not known."
Proceedings to deport him have begun.
Daifallah first visited the Air Balloon Pub near Cheltenham at 12.45pm on May 14 where police were called after he made offensive comments to a barmaid.
When officers arrived Daifallah was no longer there but he had left a trail of stench behind him which was his 'calling card'.
He then moved on to Waterstones bookstore in Cirencester where he sprayed the brown substance all over a toilet in the coffee shop.
Staff noticed the smell but it was not until after he had left that they discovered a 20 metre area of 38 shelves, from the classics to the children's section, had been doused in the foul substance.
In total 706 books were contaminated, most of them in the children's section.
Two days later at 11am Daifallah visited the Tesco store in Quedgley where a shopper saw him reach into his bag and produce a jet of brown fluid over the frozen chips.
He then moved on to the wine section where a member of staff saw a fine vapour come out of his bag and on to the wine, leaving the brown substance over the shelves.
Daifallah then drove four miles to the Morrisons store in Abbeydale where an employee in the wine section noticed him acting strangely and gagged at the overpowering stench.
Both supermarkets were cordoned off and shoppers were locked in for safety reasons while the source of the contaminant was traced. The stores were closed for two days for cleaning and shoppers reported skin rashes and nausea.
Police officers called by staff at Tesco identified Daifallah on CCTV and arrived at his home in Bibury Road, Gloucester, while he was still spraying in Morrisons.
On searching the flat they found several bottles of the noxious mixture and several plastic sachets containing excrement marked with the names of cities on them.
They also found messages scrawled over the walls referring to biological weapons, smuggling uranium into Britain and micro-organisms being spread.
One of the messages said: "The ants get out to every direction to get food, then they bring it back to Tesco and Asda. If you poison those then you kill the ants."
A map of Gloucester with 'Contaminated 83% Ammonia' written on it was also found in his bedroom.
His house was sealed off for two weeks while forensic scientists worked out what was in the packages.
Daifallah was questioned by police about another four incidents in February last year when brown liquid was sprayed at four pubs in Stroud.
