Kolkata: After the Central Intelligence agencies sounded an alert at Chhatrapati Shivaji International Airport on Tuesday about a possible terror attack after hijacking of an aircraft, the Netaji Subhash Chandra Bose airport has also been put on alert.

The security arrangements in the national and international terminals were beefed up. Even the airport officials, who were going to the functional areas, had to undergo security check. Only after a thorough verification were they allowed to enter their work areas.

The passengers were allowed to enter the aircrafts only after multi-layer security scrutiny.

The airport officials were keeping a close watch on the CCTVs, metal detectors, other appliances and movements inside the airport.

A three-level security arrangement has been set up in the airport where the Central Industrial Security Force (CISF), state police and security officials from civil aviation would be deployed.

A senior CISF official said, “Even though there has been no information of possible terror attack in Kolkata airport, we are taking necessary measures.”
