On December 5 at 9:45 p.m., Kenta Nagahama used a bicycle to come up from behind the girl, aged in her late teens, at an intersection and rub feces into her mouth with both of his hands.
Nagahama, who has been charged with assault, admits to the allegations, telling police that the excrement was indeed his own.
Approximately 40 minutes after the incident, the suspect came up from behind another girl and embraced her. This case took place on a road about 1.4 kilometers away from the first attack.
Nagahama emerged as a person of interest for the police after the examination of security camera footage taken near the first crime scene.
