Rows between protesters and some disgruntled middle-aged passengers in a train car bound for Tiu Keng Ling on Platform 3 of the Kwun Tong Line.

A middle-aged passenger took out a metal hammer and waved it around. Protesters responded by spraying with fire extinguishers inside the train car, causing white smoke to fill there.

Protesters claimed that those passengers on the Kwun Tong Line (Platform 3) attacked the reporters, attempting to kick them. The two parties exchanged insults through the open train doors, and threw water bottles and umbrellas at each other.

A woman on the platform allegedly used her smart phone to take pictures of the protesters' faces, and the protesters tried to grab her phone. Collision between them caused the glass of a platform screen door to crack.

Nearly a hundred of Raptors and riot police stormed into the Central-bound Platform 4 and train cars, wielding batons and indiscriminately beating passengers and suspected protesters, many of who did not wear face mask or protective gear. At least two persons had their heads bleeding from baton blows. The cops wildly pepper-sprayed the passengers and made arrests.

MTR announced the suspension of train service on the Kwun Tong and Tsuen Wan Lines. The first ambulance arrived at Prince Edward Station, but the ambulance crews were unable to enter because the gates were closed.

The gates at Yau Ma Tei MTR Station were closed. The paramedics were refused entry, and cried bitterly. Later on, paramedics from St. John Ambulance arrived at the scene, and were also refused entry. Paramedics there said they once entered the station and knew there were four injured persons, but they were soon driven away by the riot police.

There were three other paramedics in the station. They were forced to 'face the wall' and stand in silence.

A special train carried the injured, ambulance crews and police officers to Lai Chi Kok Station.

Police entered Prince Edward Station not to beat the passengers, but to use appropriate force to subdue the protesters, said Yu Hoi-kwan. She said that on the night of August 31, police received requests for help from the MTR, 999 reports and relevant intelligence. She claimed that when police officers enforced laws in Mong Kok and Prince Edward Stations, they were 'professional enough to tell who is a violent protester and who is a civilian'. Reporters then questioned the ability of police officers to accurately identify the protesters, and she admitted that 'in such chaos it was really difficult to identify' real protesters. Yu said that 'strategy' was not a right word to describe police's entering an MTR station to make arrests; police would do so to enforce the law whenever necessary.

Windy Tsui did not comment directly on whether police had arrested the man in blue who allegedly beat passengers with a hammer in the train car. She said that police operation was still underway, and she declined to rule out more arrests. For non-protesters who were attacked by Raptors with batons, Tsui said that situation was chaotic and the police officers were using minimum force to stop the violence; she also said that some protesters had changed into civilian clothes. As to what minimum force was, and why reporters were refused entry into Prince Edward Station, she asked the reporters to put their questions at the regular police press conference today.
