The 2019 Prince Edward station attack (Chinese: 831太子站事件), or 31 August MTR station incident, refers to an incident in which Hong Kong police allegedly indiscriminately attacked passengers while arresting alleged protesters who were returning home via Prince Edward station, on the night of 31 August 2019, after a protest was held that same day. The event was described as the police version of the 2019 Yuen Long attack, and the police have been criticised as acting like terrorists. Rumours have been circulated that several protesters were beaten to death at the station, but the police have rejected allegations. However, a mourning vigil was set up by a group of residents outside one exit of the station.
