A man indicted over the landing of a small drone on the rooftop of the prime minister’s office in Tokyo is also suspected of violating the explosives control law, sources said late Friday.
The Tokyo Metropolitan Police Department suspects Yasuo Yamamoto, 40, of Obama in Fukui Prefecture, of illegally tampering with the ignition sources of flares attached to the drone, the sources said.
According to the indictment filed against Yamamoto by the Tokyo District Public Prosecutors Office on Friday, he flew the drone carrying a payload of slightly radioactive sand in the early hours of April 9.
Yamamoto was charged with disrupting the duties of employees at the prime minister’s office, after the drone’s April 22 discovery forced them to contact security guards.
Yamamoto has said he had flown the drone in a show of opposition to restarts of the nation’s nuclear reactors, sources familiar with an investigation said.
He has described this as more than a demonstration but less than an act of terrorism, the sources added.
