Out-of-control Ryan Park admitted he used an imitation firearm on February 14, last year, at Tesco on Renfrew Road leaving a shop worker “fearful of her life.” The 18-year-old thug was only 17 at the time when he entered the supermarket wearing a balaclava and in possession of a BB gun. “The accused instructed Ms Judge to be quiet by putting his finger to his mouth and telling her to ‘shush.’ “Ms Judge thereafter alerted witnesses Stobo and White to the foregoing via her headset stating, ‘Darren, Darren, I’ve just had a gun pointed at me.’ “Witness Stobo immediately attended on the shopfloor and observed Ms Judge to be shaking and in a frightened state.
