Japanese police on Friday arrested the man who claimed to have landed a drone with trace amounts of radiation onto the roof of the prime minister's office, NBC News reported. Yasuo Yamamoto, 40, turned himself in to Fukui police, declaring that he had flown the drone, Japanese public broadcaster NHK reported. After the drone landed, investigators discovered a blog believed to be Yamamoto's, which documented his preparations for the stunt. "In order to prevent the restarting of nuclear reactors, one can't rule out terrorism," one blog entry says.
