59-year-old suspect arrested after calling government office intermittently for 11 hours Saitama. He has denied the charges against him during the investigation.

The suspect appears to have been angry that he received a phone call from the city and was told that his transportation expenses for going back and forth between the hospital and his home multiple times on the same day would not be reimbursed. On the phone, he reportedly said things like, ``I'm going to make you taste hell. Let's go there now''
