A man in Japan accidentally discharges anti-bear spray inside a post office in Nagoya, prompting emergency response and hospital treatment for several people. Multiple reports say five people are taken to hospital after being exposed to the spray. The incident occurs within the post office premises, where the substance is released unintentionally. Authorities respond to the scene and arrange medical care for those affected. Police and other officials investigate the circumstances of how the spray was discharged and assess whether any additional people were exposed. The reports describe the event as an accident rather than an intentional attack, and they focus on the immediate impact on bystanders and staff who were present in the building at the time. Information available in the sources centers on the number of injured and the location and setting of the incident, with limited additional details on the man’s identity, the severity of injuries, or the precise timeline. The case remains under investigation by local authorities.
