UPCA has tightened security around the 22-yard strip for the third ODI between India and New Zealand, in Kanpur on Sunday. UPCA acting secretary Yudhvir Singh said the security officials at the Green Park Stadium have been clearly instructed to not allow anyone into the venue without a valid pass. The groundsmen too have been strictly instructed not to discuss the nature of the pitch with anyone. BCCI curator Taposh Chatterjee is overseeing pitch preparations for the crucial game. The extra security comes after the suspension of Pune curator Pandurang Salgaoncar, who allegedly agreed to tamper the pitch ahead of the second ODI in Pune.
