NEW DELHI: Most airports in the country are vulnerable to terror attacks, because local police who provide security on the city side of those are often underprepared to handle the threat, the Central Industrial Security Force has warned.The paramilitary force has sent a report to the home and aviation ministries, highlighting the security risks from the city side of airports that includes the approach road and parking area. CISF guards the terminals at 59 of the country’s key airports. It also handles security of the city side in Delhi and Mumbai, but elsewhere, that responsibility is on the local police or other government forces.Police are unable to deploy enough personnel to guard the area around airports, said the report submitted in September. CISF has offered to provide security on the city side of the remaining airports as well, but for that it will need an additional 4,000 personnel.“The report has flagged that the city side security is not a priority of the state police and proper deployment of force is rarely done,” said a government official, who is aware of the content of the report.The report explains that preventing an attack from the city side of an airport is challenging, as huge volume of people enter the airport area, he said, speaking on the condition of anonymity. “The report has said that it is difficult to identify a terrorist among them and, hence, creating deterrence on the city side is extremely essential and manpower is required to be sanctioned for it.”CISF director-general OP Singh confirmed to ET that it had sent a report to the government, but refused to divulge the details. “We have submitted a report on various security aspects to the government,” Singh told ET. Its content is “confidential”, he added.The report has come at a time when the government is working on a plan to depute CISF at all 100 operational airports, including those it currently guards. The force is also facilitating reforms to make flying hassle-free. CISF has abolished cabin baggage tags at 13 airports and is working to roll out web-based check-in at all airports.A senior CISF official said handing over the responsibility of guarding all airports to CISF would strengthen airport security further. “A passenger is frisked only at the departing airport.A passenger, who boards a plane at a non-CISF-manned airport, can smuggle in objectionable items inside the aircraft and may use it at a large airport upon arrival. To make the system fool proof, it would be better to have CISF at all airports,” said the official, who did not want to be named.To meet these requirements, CISF said it will have to hire about 19,000 men over five years, including the 4,000 who it will need immediately.
