A fleet of interceptor drones is introduced by the Tokyo police department. The Japanese capital has strengthened it vigilance against suspicious drones that could potentially be used for mischief or even terroristic purposes. For instance, a tiny amount of radioactive sand was flown by a drone onto the roof of the office of the Japanese prime minister as part of the protest against the nuclear energy policy of the Japanese government.

Although the said drone incident earlier this year was not a serious threat, it served as a wake-up call for the authorities. In anticipation of possible serious drone threats in the future, the Tokyo police department has recently announced that it will use a fleet of interceptor drones equipped with nets to hunt and capture suspicious or unauthorized drones in the Tokyo sky. This will be a preemptive effort that will prevent possible serious incidents. The drone interceptors will also be equipped with other advanced tools.

Based on the recent reports of The Asahi Shimbun and the Asian Review, the Tokyo police will initially deploy one drone interceptor on an experimental basis starting this month. A more comprehensive with wider area of coverage operation will be launched by February next year. The fleet of drones will primarily protect the important government buildings in the city, which include the Imperial Palace and the National Diet.

Tokyo's police department is anticipating the possibility of terrorist attacks using drones. One possibility is that terrorists could use drones to drop explosives in highly populated areas or on important buildings in the city. The interceptor drones will also be equipped with radar and jamming instruments.
