On 5 January 2022, Lam announced new warnings and restrictions against social gathering due to potential COVID-19 outbreaks. One day later, it was discovered that Siu attended a birthday party hosted by Witman Hung Wai-man, with 222 guests. At least one guest tested positive with COVID-19, causing many guests to be quarantined. Sui later said that his attendance was part of community engagement and to meet stakeholders.

We will closely monitor our intelligence and see whether such acts are happening online."

In January 2023, Siu said that fake news about police must be corrected within 2 hours, and said that fake news had a big impact on the 2019–20 Hong Kong protests. In February, Siu disagreed with a reporter who asked if police were too focused on the national security law, after reports showed that crime had increased 10% from 2021 to 2022.
