Residents in Tseung Kwan O are reporting a series of unprovoked physical assaults by individuals dubbed the “bumping group,” according to reports shared on the social media group “Tseung Kwan O Plaza.” The incidents involve strangers intentionally colliding with pedestrians in local shopping malls, with recent victims including a father walking with his young daughter in Po Lam.
Reports of deliberate collisions
On July 6, a resident identified as Natalie Wong posted an alert on the “Tseung Kwan O Plaza” Facebook group regarding an encounter on July 5. According to Wong, her husband was walking near a McDonald’s in a Po Lam shopping center when an individual intentionally collided with him. The father did not pursue the person, as he was with his daughter and in a hurry, but he chose to warn others of the behavior.
The post prompted further accounts from residents who claim the issue is widespread across the district. One resident reported following a man who was intentionally bumping into people along the street until he reached Ying Ming Court. Another resident described an encounter at a Po Lam mall involving a person wearing sunglasses who walked at an angle to strike them. Reports of similar behavior have surfaced from malls near the Tseung Kwan O and Hang Hau MTR stations, with witnesses describing the perpetrators as men between the ages of 25 and 40.
Residents have identified a specific individual, described as a woman in a pink suspender top, who is allegedly active in the Po Lam and Tsui Lam areas. Witnesses claim she not only initiates physical contact but has also falsely accused male victims of indecent assault following the collisions.
Tactics used by the “bumping group”
Beyond simple collisions, residents have documented more aggressive tactics. Some individuals reportedly use their feet to trip passersby while pretending to use their mobile phones. In another instance at a Hang Hau shopping center, a witness reported being struck in the chest by a man estimated to be over 1.8 meters tall, who fled the scene immediately after the impact.

Observers suggest these targets are often chosen strategically. According to community commentary, the perpetrators appear to focus on those walking with children, the elderly, or women, likely under the assumption that these individuals are less likely to pursue them. One resident also alleged that a man frequently bumps into women before calling out to his wife, describing the behavior as predatory.
The pattern of behavior reported in Tseung Kwan O suggests a trend of opportunistic harassment that exploits public spaces. From a community safety perspective, the reliance on victims being too startled or occupied to respond allows these individuals to continue their actions. Documentation and the collection of specific details remain the primary tools for residents seeking to address the issue through official channels.
What happens next
Residents are discussing potential strategies to mitigate these encounters. A common recommendation among community members is to record the exact time and location of any incident—specifically noting nearby storefronts—to assist mall management in retrieving CCTV footage. If evidence is successfully recovered, residents may consider filing formal police reports.

Additionally, some community members have encouraged witnesses to photograph those they identify as repeat offenders and share the images within the local social media group to increase public awareness. While these actions are intended to serve as a deterrent, the effectiveness of such measures depends on the ability to link specific individuals to the reported patterns of behavior.
