Police also found out that the glass bottle used for the explosive contained dozens of small nails and other metal objects -- apparently to make the bomb more lethal.

A total of 58 students were injured when the bomb exploded at Hikari Senior High School in Hikari, Yamaguchi Prefecture. Most of the injuries were minor.

The bomb burst into flames and exploded with a loud bang as it landed just in front of the teacher's desk, spraying the classroom with glass and nails and spreading white smoke, according to witnesses.

Students were taken to hospitals for cuts as well as nausea and eye and ear pain. One student suffered a broken finger.

The suspect reportedly told police he had a grudge against a group of students who had teased him about his shyness.

Some students said the boy kept to himself so much that he was often the target of teasing, although they said they did not believe it amounted to bullying.
