The organisers of Indian Grand Prix clarified that 'Book My Show' remains their only official ticketing vendor and warned the fans against ticket frauds. It has come to the notice of the organiers, Jaypee Sports International Ltd, that some frivolous websites are claiming to be authorised ticketing partners and offering to sell tickets at a lower cost. Apart from season tickets, special Sunday tickets for October 28 are available on www.bookmyshow.com and are also available in some shopping malls and Cafe Coffee Day outlets in key metros.
