Conmen have tricked festivalgoers in Warwickshire into buying fake tickets.
Trading standards officers have already received complaints from people who bought tickets from ticket touts and classified adverts on websites.
In one case, the buyers only became aware of the scam when their tickets did not arrive and they contacted a person whose identity had been stolen.
Officers are also aware that some consumers are purchasing ‘print at home’ tickets from ticket touts, only to find on arrival at the venue that the ticket is not valid because an identical ticket had also been printed off and already used.
Trading standards officers are warning that only official ticket websites should be used and sellers should be researched online to check whether anyone has complained about them.
