Hundreds of young people threw stones and broke a glass door at a police station in Okinawa Prefecture late last week after a police officer allegedly hit a high schooler with a baton.

The Okinawa Prefectural Police believes that the attacks were prompted by social media posts detailing the incident between the high school student and a police officer, which followed a minor collision early Thursday.

According to police, young people threw stones, sticks, bottles, firecrackers and eggs at the Okinawa Police Station in the city of Okinawa from around 11 p.m. Thursday until 4 a.m. Friday. The glass door of the police station's main entrance, windows of police vehicles and an electric bulletin board were broken. Riot police were dispatched but no injuries were reported.
