Gurugram, Nov. 21 -- A Gurugram police constable was mowed down by a speeding 18-wheeler truck in a bid to avoid vehicle inspection at Gwal Pahadi post on the Gurugram-Faridabad road on Thursday, police said. They added that the driver had been identified and would soon be arrested. The deceased was identified as 32-year-old Ajay Singh. He was stationed at the Gwal Pahadi post and hailed from Rewari. Singh had got married just seven months ago, and was the family's only provider. The truck, which was carrying gravel, also rammed a loaded pickup van parked on the roadside-tossing it several feet in the air-and the barricades, whose mangled metal parts ruptured the truck's diesel tank and punctured its front tyre, forcing it to stop 200 metres ahead of the spot. Singh was standing right next to the van at the time, police said. The incident took place at 2.40am right in front of the post where a five-membered police team was engaged in routine vehicle checking. One of Singh's colleagues said the truck was enroute from Gurugram to Faridabad. "The truck showed no sign of stopping or slowing down despite the checkpoint being visible from afar on that straight stretch." Sandeep Turan, public relations officer of Gurugram police, said the driver tried to flee but the ruptured fuel tank and blown-up front tyre made it impossible for the vehicle to move. He then abandoned the vehicle and fled on foot....
