2019年8月31日晚上，警方於九龍旺角太子站，無差別襲擊乘客。最初反對示威的乘客挑釁並襲擊示威者及巿民，示威者不滿，其後雙方口角及動武，之後多名防暴警員及特別戰術小隊成員（速龍小隊）衝入太子站往中環的月台及列車，以警棍及胡椒噴霧等武器無差別襲擊車廂內的乘客，網絡有消息質疑若干人被警察毆打致死。有人將事件視為「元朗7‧21恐襲的警察版」。
今日是8‧31事件一周年，有市民中午起陸續到太子站外獻花及「三鞠躬」悼念，但警方和港鐵清潔工不斷清走鮮花，又有票控個別獻花市民「亂拋垃圾」。人稱「Lunch哥」的David 在太子站內舉手表示「五大訴求 缺一不可」，遭票控對「乘客造成滋擾」。
今日亦是人大常委落閘封殺真普選的「八三一決議」6周年，社民連梁國雄、吳文遠、黃浩銘及陳皓桓到中聯辦外抗議，要求中共撤銷「八三一決議」，及廢除《港版國安法》。4人被警方票控，指違反限聚令。
晚上7時半，數十人應網民號召在尖沙咀太空館外館外「夜祭」警務署長鄧炳強，表達對香港警察濫捕濫暴濫告強烈不滿。現場展示紙製「鄧炳強之墓碑」，下款「有心香港人不敬」，燒街衣拜祭。
On the evening of August 31, 2019, the police attacked passengers indiscriminately at Prince Edward Station in Mong Kok, Kowloon. Initially, the passengers who opposed the extradition protests provoked and attacked the protesters and citizens. The protesters were angry and fought back. Afterwards, many riot police and Special Tactical Team members entered the platform and train at Prince Edward Station towards Central and used batons and pepper spray indiscriminately to attack passengers in the carriages. Information on the Internet alledged that several people were beaten to death by the police. Some people regard the incident as “the police version of the Yuen Long July 21 terrorist attack.”
Today is the first anniversary of the August 31 incident. Since noon, citizens have successively presented flowers and “3 bows” to mourn at the Prince Edward Station. However, the police and the MTR cleaners kept clearing the flowers, and some people were charged for “littering” flowers. David, a frequent “Lunch with You” protester, raised his hand signalling “5 Demands, Not One Less” at Prince Edward Station was cited for “causing a nuisance to passengers.”
Today is also the 6th anniversary of the “August 31 Resolution” of the Standing Committee of the National People’s Congress that banned true universal suffrage in Hong Kong. Leung Kwok-hung, Avery Ng, Wong Ho-ming and Chan Ho-won went to the Central Liaison Office to protest and demand that the CCP revoke the “August 31 Resolution” and abolish the Hong Kong version of National Security Law. All 4 were charged by the police for violating the social distancing order.
At 7:30 pm, dozens of people responded to the call of netizens to a “night memorial” outside the Planetarium for Police Commissioner P K Tang, expressing their strong dissatisfaction with Hong Kong police’s indiscriminate arrests, charges and brutality. The paper “Tombstone of P K Tang” was displayed on site, and signed “Disrespectful Hong Kongers”, burning joss, incense and other offerings.
