Pakistan-based Lashkar-e-Taiba has acquired more than 50 para-gliding equipment from Europe, setting off alarm bells in the government that these could be used to carry out air-borne suicide attacks in the country.
The intelligence input which came barely days ahead of Republic Day celebrations has prompted authorities to ensure a tight air security around all vital installations, official sources said here on Friday.
The input about movement of overground workers, owing allegiance to LeT, in Europe led the sleuths to find out that they were on a shopping spree for para-gliding equipment, the sources said.
Security agencies have carried out mock drills in different areas in the country as part of the exercise to prevent any air-borne suicide attack by LeT terrorists.
The input bears significance in view of the fact that government has already put all Air India planes operating in the country's neighbourhood on high security alert following intelligence reports from Western agencies that the LeT and other terror groups were planning to hijack a flight.
Radars located at strategic locations have been tuned to intercept all low flying objects and authorities are not taking any chances, sources said.
A no-flying zone is already in place in capital's Luytens zone which houses the Rashtrapati Bhavan, Prime Minister's Office and key ministries like home, defence, finance, external affairs, among others.
Ahead of the Republic Day, elaborate air defence measures, including deployment of anti-aircraft guns, have also been taken to check possible intrusion of air space.
Besides, helicopters of the Indian Air Force will hover over the areas around Rajpath and all along the route of the Republic Day parade.
Earlier, intelligence reports suggested that Pakistan's Inter-Services Intelligence had directed the militants operating in Jammu and Kashmir to use explosive-laden 'Toy Planes' to hit VIPs in the state and the national capital.
