Man arrested for flying drone found at Japan PM office

A man was arrested Saturday for allegedly flying a small drone carrying traces of radioactive material to the Japanese prime minister's office to protest against the government's policy to promote nuclear power, police said.

Yasuo Yamamoto, 40, was arrested on suspicion of forcible obstruction of business and interfering with the operations of the office of Prime Minister Shinzo Abe by leaving the drone on the roof of the office's building, Kyodo news agency reported.

He has admitted to the allegations, police investigators said.

The arrest comes after the resident of Obama city in Fukui Prefecture, where several nuclear plants are concentrated, presented himself to police in the western prefecture on Friday evening.
