The Delhi Police has deployed over 400 kite catchers and fliers on rooftops and other sensitive locations in the fort area to counter any threats from sub-conventional aerial platforms. A five-kilometre area around the Red Fort has been marked as a "no kite flying zone'' till the tricolour is hoisted.
Anti-drone systems from Defence Research and Development Organisation and other security agencies are also being installed, police said.
"We have installed high resolution security cameras at and around the Red Fort and their footage is being monitored round the clock. This time, the number of invitees has increased to 7,000. FRS cameras have also been deployed at the entry point of the Mughal-era monument," a senior police officer said.
Lunch boxes, water bottles, remote-controlled car keys, cigarette lighters, briefcases, handbags, cameras, binoculars, umbrellas and similar items will not be allowed at the Red Fort premises, he said.
Dependra Pathak, Special Commissioner of Police (Law and Order) said provisions of Section 144 have already been instituted in Delhi. Anyone seen flying kites, balloons or Chinese lanterns from August 13 to August 15 till the end of the programme at Red Fort will be punished.
"Kite catchers have been deployed with necessary equipment on strategic locations and they will prevent any kind of kite, balloon and Chinese lanterns from reaching the function area. Radars will be deployed at Red Fort to counter any threats from sub-conventional aerial platforms and manned or unmanned flying objects," he said.
