Fiscal depute Gillian Sim's Subway sandwich contained Stanley knife Sandwich chain Subway sold a tuna baguette with a Stanley knife blade in it to a lawyer. Fiscal depute Gillian Sim described how she bit into the tuna and cheese roll and discovered a three inch long blade in it. A sheriff ruled on Friday that the blade must have been in the baguette when it was sold to Miss Sim at the Dundee branch of Subway. Sheriff Richard McFarlane said he had no doubts over the credibility and reliability of Miss Sim or her fellow prosecutor Paul Miele who watched as she pulled the blade from her mouth. The sheriff said: "I am satisfied the blade was in the sandwich at the time it was sold to her. I have no issue with the credibility and reliability of the witnesses. Gillian Sim told the court they went to the Subway shop to buy filled rolls for lunch. She ordered a tuna sandwich. She started eating her sandwich and on the third bite found something hard on her teeth. She discovered a Stanley knife blade, which she then removed from her mouth. The sandwich was never out of her sight. There was no opportunity for anyone to put the blade in her sandwich. Miss Sim, who was working as a prosecutor in Dundee, told the trial: "We went back to the office and went into the kitchen area to sit and eat it there. I had the first bite and it was fine and then had another couple and bit down on something hard. I kept whatever it was between my teeth. I pulled out what was in my mouth and found out it was a Stanley knife blade. I put the sandwich down and pulled it out of my mouth. Paul asked what was up and I showed him and then I said, 'what do I do with it?' I thought with it being a blade I better put it in something. I put it in a pot. Miss Sim said she then told police officers working in the court about what had happened and was advised to report the find to environmental health. She said she accepted that some people might not like lawyers, and particularly prosecutors, but denied that the blade could have been placed in the roll by a disgruntled criminal. Paul Miele said: "We went back to the fiscal's office. At the time there was only me and Gillian there and we sat down to have lunch. I remember Gillian was eating hers when she said 'yeuch' or something like that. I remember laughing and saying 'is it a hair?' Then she took some food from her mouth and also a blade which had been in the sandwich. Obviously I was very surprised there was a blade in the sandwich. Under the auspices of Edinburgh-based SS North Ltd, the company was prosecuted for providing a roll with a craft blade in it at the Dundee branch of Subway on August 16 2011. It was alleged to have sold "a filled submarine roll to the purchaser's prejudice, which was not of the nature, quality or substance demanded by the purchaser, in that the roll had a craft blade or similar instrument within its contents." The submarine roll - which contained tuna, cheese, mayonnaise, cucumber and gherkins - was sold from the company's store in the Overgate Shopping Centre. Sheriff McFarlane said he was "intrigued" by the size of the blade found in the roll. Despite establishing it was in the roll when sold, he cleared the company on the grounds of due diligence. He said he accepted "on the balance of probabilities" that the company had done everything possible to ensure they followed appropriate food safety practices. He said there was no evidence to suggest any of the staff were disgruntled or that the blade had been left behind by any tradesmen working in the shop. SS North Ltd was acquitted.
