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.
