The Saga Family Court issued an order Friday to send to a medical juvenile reformatory a 17-year-old boy accused of hijacking a bus for 15 hours, killing a passenger and wounding five people in May.

Judge Katsuki Nagatome said the boy needs medical treatment for a dissociative disorder. He also said the court recognizes that the boy was mentally competent to take responsibility for his actions at the time of the hijacking.

At the reformatory, the boy will be put under psychiatric observation and receive counseling and medical treatment.

The court made the decision after examining reports containing details of the boy's life and his psychiatric evaluation.
