ByTwo men employed with the real estate search portal, Housing. com, have been detained for using a drone camera near the Bhabha Atomic Research Centre (BARC) and triggering a terror scare. The two, who work as data collectors for the portal, were spotted by a Tata Institute of Social Sciences (TISS) professor, who then alerted the police.The Anti-Terror Cell (ATC) of Trombay police have now demanded an access to the portal’s entire data to determine if any objectionable content was recorded by the drone earlier. Sources said an ATC team has been assigned to go through the portal’s computers and hard disks. The team was in the portal’s office till late night.DCP Sangramsinh Nishandar said using drones in Mumbai without prior permission is not allowed.The TISS professor, who was stepping out of the institute, noticed a man operating a drone. Knowing that this was a breach, he began recording the episode on his cell phone. “When they noticed that they were being shot, the operator recalled the drone to the ground. They packed into a car and sped away,” said a TISS source.The two-minute video shows the operator controlling the drone, recalling it after realising that he was being filmed, packing it and speeding off in the car. A source at Trombay police station said, “TISS campus has two gates. One of them is closer to one of the Bhabha Atomic Research Centre (BARC) entries. When we received the call, there was a fear of a terror angle in the case.”Teams of policemen then rushed to the campus in four vehicles. The men’s rush to escape fuelled their suspicions. They began searching for the two on the basis of the video footage and the number plate of their Toyota car. “It was a rented car. The rental service told us that it was rented by the real estate portal,” said DCP Nishandar.After tracing the men, the unmanned aerial vehicle (UAV), later identified as a Phantom DJI costing approximately Rs 80,000, was also confiscated. Police said they found around 300 photos in the UAV, taken on the Sion-Trombay stretch as well as other parts of the city of various buildings, real estate projects and construction sites.“Nothing objectionable was found except photographs of real estate sites. Many UAVs are in use in the city but have prior permission by the police. In this case, since BARC is a sensitive area, the police swung into action immediately. There is no footage of any vital installations in BARC, since it was not in the drone’s range,” said the DCP.A Housing.com spokesperson, meanwhile, told Mirror that they had no idea about the incident. “We have not been contacted by the police. We will be in a position to respond when we are approached,” said Dimpee Shah.
