Former lawmaker Muneo Suzuki has received letters containing rifle bullets at his Tokyo and Hokkaido offices, while a similar letter has been sent to the residence of former Foreign Minister Yohei Kono, police said Monday.
The three letters contained bullets and notes signed by a group calling itself "Kenkoku Giyugun Kokuzoku Seibatsutai," a rough translation of which is "nation-building volunteers corps to conquer traitors."
Police said they are treating the incidents as cases of intimidation and violations of the Explosives Control Law. They suspect a connection with 13 other similar cases.
