Message from Thames Valley Police.
A male is approaching users of Liston Road car park and its service road, advising them that they are parked on double yellow lines and need to pay a fee via the payment machine. He then takes the payment card, runs off and withdraws large sums of money from nearby cashpoints. Please: DO NOT entertain such conversations with anyone. Official parking wardens are always appropriately dressed in corporate clothing and have official ID badges. If in doubt seek advice or call the the number on the car park noticeboard to help check. If in doubt, call the police for advice.
