Pubcaster unaware of what caused incident
TOKYO — Bullets were sent to four of the offices of NHK, including the pubcaster’s Tokyo broadcasting center, in what is being investigated as a terrorist threat.The incident follows an arson attempt Sunday at the NHK office in Fukuoka, the biggest city on the southern main island of Kyushu. The pubcaster has no idea what prompted either incident. The bullets arrived at the NHK Tokyo office Monday and at offices in Sapporo and Nagano on Tuesday. Postal authorities intercepted a similar package addressed to the NHK office in Fukuoka. Bullets are often used by gangsters and rightists in Japan as threats to potential victims. The bullets came with a piece of paper printed with the word “Sekihotai,” the name of a rightist group that launched an attack on a provincial bureau of the Asahi Shimbun newspaper in 1987, killing one journalist and wounding another. On Sunday, a man set fire to NHK’s office in Fukuoka using a gas cylinder. The fire caused no serious damage. Security cameras captured the man on tape, but police have not yet made an arrest. The two incidents do not appear to be related, but police are continuing to probe possible links.
