A Delhi Police head constable, part of the escort team of former Jammu and Kashmir chief minister Farooq Abdullah, was injured when the car convoy collided with a nilgai on Delhi-Mumbai expressway in Rajasthan's Dausa district, officials said on Saturday. The accident occurred near the expressway exit in Bhandarej around 1.45 pm on Friday when the National Conference leader was en route to Ajmer. Abdullah was in another vehicle, while the escort vehicle had four police personnel, including head constable Pappuram Meena, officials said. Meena was driving the Innova vehicle when it collided with the nilgai. "The injured head constable was taken to the district hospital where he was given primary treatment and discharged later," Sadar police station head constable Arvind Kumar said. He said that as soon as the accident occurred the other vehicles including the one carrying Abdullah stopped. The members of the escort team then left for Ajmer in another vehicle of the convoy.
