Time: 13.24

Place: Knightsbridge, London

Victim: Kym, 26, Qantas flight attendant

Crime: Chocolate chip and nut biscuits

Every week we will be pouncing on lunch time shoppers to see what they've been buying. They may have been stocking up on those dull essentials - or perhaps they've been treating themselves or their loved ones. Yesterday, Holly Davies found Kym coming out of London's Harvey Nichols, where the only thing she bought was a packet of biscuits (price pounds 2.95). "Whenever I'm in London, I stop by Harvey Nics to top up my mum's biscuit barrel: she saves the tins to brighten up her kitchen. It was a choice between shortbread or chocolate chip - I always say, if in doubt, go for chocolate."
