Ahead of the Amarnath Yatra being flagged off today, Abhay Vir Chauhan IG CRPF Jammu sector held a meeting of senior CRPF officers of units deployed in Jammu region at Sector HQ Bantalab earlier today. Security of Base Camp Bhagwati Nagar and the yatra route were discussed. Radio frequency based ID tags have been installed on vehicles so that the CRPF control room will know whenever the vehicles pass by the four reception centres on the two routes. "If we don't receive a signal from a vehicle we'll inform IG Control room and naka points," said Commandant PP Pauly, 73 Battalion CRPF at Bemina.
