EYE IN THE SKY
More than 30,000 high-resolution pictures, each at 14 megapixels, were shot from an altitude of 100m using these drones over 10 days. A backend team stitched all this together to create an ‘ortho map’ (or a digital surface map). This was later converted into 3D visuals that were fed into a mobile app only the security team could access.
“This helped police in identifying vulnerable points and decide on personnel deployment,” said K Senthil Kumar of Centre for Aerospace Research, Madras Institute of Technology, Anna University.
Security personnel were stationed on terraces along the route, besides at metro rail stations that are vantage points. On the ground, four officers in the rank of DIG and 16 SP-rank officers have been leading a team of 10,000 police personnel to monitor security of the visiting dignitaries. Three SPs are coordinating with internal security officials and Chinese security officials, with assistance from six assistant commissioners of police, 16 inspectors of police, 48 sub-inspectors of police and 400 other personnel.
A quick reaction team (QRT) is stationed at the airport. Another group of three SPrank officials are in charge of the periphery of the hotel in Guindy, where Xi is staying. As many 60 as QRT members have been deployed at the hotel.
Two DIG-rank officials, eight SPs, 30 ACs, 90 inspectors and 270 SIs have been deployed along with 3,000 police personnel on the East Coast Road till Muttukadu outside the city limits. The rest of the personnel have been stationed in and around Mamallapuram. After finalising the routes to be taken by PM Narendra Modi and Xi, police have also worked out three contingency routes. Chennai: A couple of hours before Xi Jinping landed in Chennai on Friday for the informal summit with PM Narendra Modi, police detained 12 Tibetans for trying to stage protests at the airport and near the Chinese president’s hotel. A group of 250 Chinese nationals had also gathered outside the hotel to greet their leader. Six Tibetans were picked up after they mingled with the media and the public crowding outside Grand Chola, where Xi is staying, and raised slogans around noon.
An hour later, police at the airport detained a group of six Tibetans who had just flown in from Bangalore on suspicion that they were planning to stage a protest. Earlier, on Thursday night, Pema Ngodup, a Tibetan journalist with the Washington-based Radio Free Asia — who said he had come to cover the summit — was detained by police for not carrying valid ID.
Earlier this week, Chennai police arrested Tenzin Tsundue, a Tibetan activist and writer, as well as nine other activists. The arrests came after central intelligence agencies alerted Chennai police about possible protests by the outfits Tibetan Youth Congress and Students for Free Tibet-India.
Among those travelling to Chennai are also some 250 Chinese nationals living in different parts of the country who wanted to catch a glimpse of Xi. Hu Shu, a banker in Bengaluru, sought to stress the positives such summits can achieve. “The need of the hour is to resolve conflict between the two countries. There are several Chinese working here and vice versa. We hope the outcome is in everybody’s best interests. It would make us all happy,” he said.
