North Norfolk: Lotto Prize Unclaimed
A Lotto prize of £73,263 has yet to be claimed in the North Norfolk District.
National Lottery players are being urged to double-check their tickets.
The search is now on to find the owner of the winning ticket, bought in the North Norfolk District who matched five numbers and the bonus ball in the Lotto draw on Saturday 11th August 2012.
The winning Lotto numbers on that date were 1, 5, 14, 18, 34, 44 and the bonus ball was 23.
The ticket-holder has until Thursday 7th February 2013 to claim their prize.
If no-one comes forward with the winning ticket before the prize claim deadline, then the prize money, plus all the interest it has generated, will go to The National Lottery Good Causes - adding to the £28 billion already raised through sales of lottery tickets since The National Lottery launched in November 1994.
A National Lottery spokesperson said: "We're desperate to find this mystery ticket-holder and unite them with their winnings - this amazing prize could really make a huge difference to somebody's life.
We're urging everyone to check their old tickets again or look anywhere a missing ticket could be hiding. Try checking in the pockets of clothing, in wallets, bags and down the back of the sofa - someone out there could literally be sitting on a fortune!
We have the champagne on ice and our fingers crossed that the lucky winner comes forward to claim their win."
To jog Lotto players - memories, Heatwave by Wiley ft. Ms D topped the UK singles chart at the time, while Conor Maynard was at the top of the album charts with Contrast.
Sports fans will remember that it was the last day of action at the London 2012 Olympics. Team GB added to their medal tally with a gold for Anthony Joshua in the super heavyweight boxing final and a silver for Sam Murray in the modern pentathlon.
Anyone who believes they have the winning ticket for any of the National Lottery draws within the 180-day deadline should call the National Lottery Line on 0845 910 0000.
