Security personnel have been deployed at runways, checking area, terminal premises and parking zones for round-the-clock surveillance. Passengers are being strictly checked at the entry points,” said an official.

Total 111 CCTV cameras have been installed, including 67 at the Domestic Terminal and 44 at Terminal 2 to keep a close eye on any kind of suspicious activities.

“An alarm will be automatically raised if any suspicious object is found lying inside the terminal for over 15 minutes without any possessor. Passengers have been advised to do early check-ins to get their boarding passes,”the official added.

The SOP will remain in force till further order by the Centre.
