The demonstrations on 4 August began with a permitted march in Tseung Kwan O, starting from Po Tsui Park at 2 pm, with organizers stating around 150,000 protesters in attendance.
During the rally, protesters threw bricks towards the police station breaking windows. They chanted “Hong Kong police knowingly break the law” and “Shame on the corrupt police”. Police officers then appeared with police dogs and protesters dispersed. At night, the crowds occupied Po Shun Road. Riot police arrived to disperse crowds, and they unreasonably attacked a passer-by.
Another rally appeared in Kennedy Town after the Tseung Kwan O rally. By the evening, protesters defied the police ban and marched towards Sheung Wan. However, by about 7 pm police deployed tear gas canisters and routed the group to Causeway Bay, where thousands of protesters setup blockades and occupied areas of the shopping district. Then again by 10 pm riot police attempted to clear the streets with the use of tear gas.
Near the end of the Kennedy Town protest, some protesters went and blocked the Cross-Harbour Tunnel and a small group of protesters sprayed graffiti on the sculpture at the Golden Bauhinia Square. At the same time, a group of protesters gathered at Wong Tai Sin police station, protesting their way of force to the residents in the 3 August protest. Fearing that the police may deploy heavy force following August 3 scuffles, some protesters opted to occupy sections in Ngau Tau Kok and Kwun Tong. At night, various protests and police operations were done in Mei Foo, Wong Tai Sin, Tin Shui Wai, Ma On Shan, and Lam Tin. Eastern Harbour Crossing and Tseung Kwan O Tunnel were temporarily blocked during the protests.
