Police sent a 48-year-old man to prosecutors Wednesday after he allegedly broke into a cram school in Saitama Prefecture while completely naked. Authorities believe he may have also been involved in roughly 20 incidents that took place in the 90 minutes before his arrest ¡ª including a fatal hit-and-run and multiple assaults ¡ª with at least 10 people injured in total, according to a report from Nikkei.

The suspect, Daisuke Nishimura, was arrested Monday evening at a cram school in the city of Soka. He faces initial charges of trespassing and assault after allegedly striking a 59-year-old male staff member with a mug and injuring a 14-year-old girl by grabbing her arm.

Saitama Prefectural Police said the suspect¡¯s rampage appeared to have begun at around 8:15 p.m. in the nearby city of Kawaguchi. The first emergency call believed to be regarding the suspect came from a person who reported a ¡°suspicious tattooed man driving slowly through a residential area.¡±

Roughly 35 minutes later, two motorcycles were struck by a car that police suspect Nishimura was driving in the Omagi district of Saitama City¡¯s Midori Ward. One of the riders, a 46-year-old local office worker, was killed. Another man, 45, sustained serious injuries.

Several incidents police think involved the man subsequently occurred in rapid succession in Kawaguchi. At around 8:55 p.m., a naked man was reportedly involved in a car crash, then fled the scene in the other driver¡¯s vehicle.

Afterward, a naked man allegedly entered a convenience store in Kawaguchi and stole several items. In another case in the city, a taxi carrying two passengers was believed to have been carjacked by a naked man.

Police found Nishimura at the cram school in Soka at approximately 9:40 p.m., about 90 minutes after the first reported sighting of the tattooed man in Kawaguchi. He was arrested on the spot.

Police are continuing to investigate the sequence of events. They are also looking into a motive.
