Delhi Police personnel, who were till now deployed on the route to the Cardio Vascular Thoracic Surgery (CVTS) unit, where the PM has been recuperating, fanned out to different locations in the hospital premises after the fog descended around 5 am.

“Because of the fog, personnel have been asked to cover other areas of the AIIMS premises, like the Out Patient Department (OPD), Emergency and Paediatrics among others,” a senior police officer present at AIIMS said. The arrangement was made just to make sure the area is secure and there will not be any constant deployment in these areas, the officer said.

Security has also been strengthened near the CVTS unit with the deployment of more Special Protection Group men and Delhi Police commandos at the exit of the unit.
