Last night, the police fired tear gas at the Tai Koo Station and Kwai Fong Station of the Hong Kong Railway to disperse the demonstrators. Among them, a police officer at Tai Koo Station suspected of firing pepper balls at the demonstrators at close range, causing controversy. The Assistant Commissioner of Police, Michael Chan Ho, agreed that there would be dangerous situations during the arrest operation, but denied that some police officers were out of control at that time. He also stressed that the pepper ball would not directly cause harm.

Mai Zhanhao said that the police would understand the situation and review the distance of the pepper ball launcher. He stressed that in the past, when the police dealt with large-scale public activities, public safety was the primary consideration, and the safety of peaceful demonstrators, violent demonstrators, citizens and police officers was very important.

He continued that the use of force by the police was strictly regulated, and it was necessary to distinguish between peaceful assembly and violent incidents. It also meant that the police was dealing with a non-peaceful public activity, and was to intercept or arrest the demonstrators who committed violent acts. Michael Zhanhao admitted that using the pepper ball launcher at close range might make the public have a "view", but denied that the police officers were out of control at that time. Specifically, we still need to collect more information before we can comment on whether the police officers acted properly at that time.

Xie Zhenzhong, the chief superintendent of the Police Public Relations Section, said that the pepper ball launcher will turn into powder after hitting the body, and the effect is the same as that of tear water. When the police introduced it, it was tested that the pepper ball launcher can be used in a short distance, while other law enforcement departments will also use the equipment in a confined space.
