“Tokyo police are studying technology for capturing suspicious drones as part of efforts to boost surveillance of airspace above important facilities, following the recent discovery of a drone on the roof of the prime minister’s office, Jiji Press learned Wednesday.
The Metropolitan Police Department will also examine whether unidentified drones can be detected by security cameras that respond to heat sources, among other methods, government sources said.
The police arrested a 40-year-old man on Saturday over his alleged involvement in the high-profile incident, after a small unmanned aerial vehicle was found on the roof of the prime minister’s office in central Tokyo on April 22.”
