Md Sohrab was also a Rashtriya Janata Dal (RJD) MLA till 2011. The incident has sent shock waves to security agencies who consider it was a major security breach.

"The Audi came at a high speed, knocked down the Corporal and then sped away. It then swerved and smashed into a barricade. The driver got off and escaped before security personnel could reach the spot where the SUV collided with the barricade. The vehicle managed to breach three rings of security around Red Road. It could have been an explosive-laden vehicle. We have taken up the matter with the police who are in charge of security during the parade rehearsal," a senior defence ministry official said.
