A green Suzuki Kingquad 500 and red Honda TRX520FA6, were taken from the trade stalls of other vendors.

Norfolk police said investigations were continuing but no arrests had yet been made.

Research by NFU Mutual revealed that countryside crime cost Norfolk almost £1m in 2021 with quad bikes and all terrain vehicles being a top target due to “very high prices because of supply and demand”.

Anyone with information can contact Norfolk Police on 101, quoting crime reference number NC-30062022-147.
