Police on Saturday searched the home of a 17-year-old youth who was arrested Thursday for allegedly hijacking a bus in southwestern Japan the previous day, stabbing one passenger to death and injuring at least four others.

On Friday, police sent the boy's hijacking case to prosecutors. The teenager, whose identity is being withheld because he is a minor, has admitted possession of a weapon and hostage-taking, according to police.

Shortly before 11 a.m. on Saturday, a joint team made up of officers from Saga and Hiroshima prefectural police arrived at the teenager's home. Four officers entered the house carrying boxes.

The youth was arrested immediately after riot police stormed the bus shortly after 5 a.m. Thursday in Hiroshima Prefecture, rescuing the 10 remaining hostages and ending a 15-hour ordeal that began when the suspect allegedly commandeered the intercity bus in Kyushu wielding a large kitchen knife.
