OSAKA — The suspect in last Friday's massacre at an elementary school in Ikeda, Osaka Prefecture, has told investigators that he wanted to "stir up a commotion" to harass his relatives, it was learned Wednesday.

Mamoru Takuma, 37, was quoted by Osaka police investigators as saying that he held a grudge against one of his divorced wives. "I wanted to stir up a commotion to harass her. (The victims) could have been anybody (at the school)," he reportedly told police.

On June 8, Takuma was arrested after he stormed into the Osaka Kyoiku University Ikeda Elementary School wielding a knife, stabbing eight children to death and injuring 15 people.
