Matt Yeung (楊明), Sisley Choi (蔡思貝), Max Cheung (張達倫) and William Hu (胡渭康) wore PTU (機動部隊) uniforms to film TVB new film (警察故事) at the police headquarter on 31st January 2019. Sisley and Matt were given the chances to try the pepper spray and he said: “We are aware of this scene and feel like trying it personally. During the shooting on that day, the film producer and crew team were present and many police officers kept telling us to think about it again, but we are determined to try it in order to understand their sufferings.”

When asked if it was terrible after using the spray, Matt said: “It is frightening when spraying it for the first time and the police officer advised us to close our eyes as it would be painful. It resembles to putting many chilli and peppers on my face and makes me feel dizzy and difficult to breathe.”

Sisley said: “The police officer is powerful. I feel both of my eyes become swollen immediately after the spraying and need to read a poster before washing my eyes. It is quite hard to breathe when washing it.”

Checking if it affected the filming progress subsequently, Sisley said: “Nope, but it is quite suffering on the second day. I will close my eyes to rest once the camera stops rolling and feel better today. I show my respect to the officers and can feel their pain now.” Matt also understood the suffering after trying it personally and would use his tears to reduce the pain.
