At large and important airports like Delhi, Mumbai, Bangalore, Hyderabad, Kolkata, Chennai and Ahmedabad, passengers are being screened through multiple layers of CISF and airport security and a number of them are being asked to take out shoes and open hand baggages for a thorough checking.
Airlines and special teams of the CISF and airport security have been asked to conduct risk-based Secondary Ladder Point Check (SLPC) which entails frisking passengers on the air side just before entering the aircraft.
Armed Quick Reaction Teams (QRTs) of Central Industrial Security Force commandos and local police have been positioned at vantage locations around vital airports and leaves of jawans and officers are being regulated strictly so that maximum numbers are on ground at least till January 26 and in some cases even beyond that, they said.
