Deputy Commissioner (Operations) (DCP OPS) Lau Yip-shing earlier participated in the filming of a video entitled "Small Role, Critical Role". The video depicts two uniformed officers dutifully carrying out their duties during patrol. This demonstrates the value and significance of everyday police work. Mr Lau encouraged officers not to belittle their role as they all play a critical role in serving the public.
