Tokyo Metropolitan Police have arrested a man for allegedly sending threatening letters to former Supreme Court Chief Justice Koichi Yaguchi, police officials said Tuesday.

Hideo Suzuki, 68, is also suspected of having sent about 170 letters to other former chiefs of the top court and the Tokyo Family Court since November 2001.

He was reportedly dissatisfied with court rulings pertaining to an acquaintance's property inheritance, according to police.

Suzuki is believed to have enclosed razor blades in some of the roughly 10 letters he sent to 84-year-old Yaguchi.

As Yaguchi was not involved in the inheritance cases, Suzuki is believed to have been motivated by hostility toward the justice system in general, they said.

Suzuki has denied any intent to make threats.
