The decisions were taken during today’s meeting between CISF (responsible for security) and DIAL (the company modernising the city airport) officials.

“It was decided that CISF will take preventive measures and DIAL will support CISF in every possible way,” said Arun Arora, Corporate Communications, DIAL. CISF officials, though, claimed it was a “routine” meeting, and not related to Sunday’s incident in any way.

CISF officials had claimed lighting is poor in several parts of the perimeter wall — the boy had scaled it to enter the airport — and that makes guarding these areas a tough ask.

Officials said CISF is also getting in hi-tech security equipment —infrared-powered CCTVs among others — for the perimeter wall to detect intrusion. The three-layered security system, though, is still in the planning stage.

Spread over more than 5,000 acres, IGI is one of the biggest airports in the country. Of the total area, nearly 2,000 acres is the built-up space; the rest is airside area. “It is a mammoth task to guard the whole airport area,” a senior CISF official said, “because most of its boundaries are adjacent to secluded areas with no population.”
