The MTR refers to whether the relevant station can be reopened in the morning due to the police’s search. From the online clip, two groups of dissident passengers confronted each other on a moving MTR train.
The train stopped at the Prince's station, and the black man fell into the car. The two groups continued to confront each other and throw water at each other. Suddenly someone in the car took out a clam and waved to the black man outside the car, which turned into a conflict. After nearly ten minutes of disturbance, someone fired a fire extinguisher into the compartment and the smoke was filled.
Afterwards, a group of Athlon squad members armed with batons and guns entered the platform of the Prince's Station. At that time, there were many passengers on the platform and there was also a train stop. The policeman walked into the train and pushed a passenger out of the carriage, uniformed on the ground. He was wearing black clothes and wearing a black mask. There are also fragments, the Athlon team smashed one person on the platform, then subdued him, then cast a pepper spray into the compartment. There was a bloody head in the compartment.
The MTR announced that there was an emergency at the Prince Edward Station at 11 pm, but it was evacuated and closed. After the station was closed, a large number of police officers entered the lobby. More than a dozen people were subdued by the police. Their hands were tied and taken away. Some people were not wearing black clothes.
The police said that the demonstrators attacked the Dalits in the Taizi station and destroyed the facilities in the station. The police received reports of entering the MTR to stop the violence and arrest the offenders. Due to passenger conflicts in the station, the station started the evacuation procedure and called for help.
