Miles Kwan, a university student in Hong Kong, was arrested after launching a petition seeking answers about a deadly fire in Tai Po district. The blaze killed at least 159 people and displaced thousands. Kwan was detained by national security police on suspicion of sedition but is now out on bail, local media report. Authorities warned against efforts to “exploit” the fire to harm national security. Police told the BBC they will act according to the law. Public reaction was strong, with many finding the arrest “baffling.” Some see it as a repeat of Beijing's usual tactics. Hong Kong officials, including Executive Council member Ronny Tong, said the government is trying to be careful. Lawmaker Regina Ip added that the aim is to prevent a repeat of the 2019 riots. Kwan’s petition collected over 10,000 signatures quickly before being removed. His four demands echoed the protest slogan “five demands, not one less.” Many of these were later addressed by Chief Executive John Lee, who promised full support for victims, an independent fire investigation, and changes in building safety. Pro-democracy activist Samuel Chu called the arrest “baffling” since the government addressed the concerns anyway. "This is not a political campaign. It’s a human response to the tragedy," he said. Authorities have also arrested 15 suspects over manslaughter related to the fire and removed unsafe materials from buildings. One woman was arrested for a fake fundraiser linked to the incident. China’s national security office in Hong Kong threatened swift action against anyone inciting unrest, calling the 2019 protests “black terror.” John Lee vowed to punish those sabotaging relief efforts. Former district councillor Kenneth Cheung, among those arrested, said the fire concerns all citizens regardless of politics. "Not everything is about politics," he said. Political experts accuse Hong Kong officials of using heavy control to limit grassroots relief efforts. Social media showed frustration over the arrests and government actions. Many questioned if asking for truth now counts as incitement. No government official has resigned or been arrested. The 15 detained for manslaughter are construction workers and bosses. The city will hold a Legislative Council election soon, only open to pro-Beijing candidates, a move criticized by some residents mourning the tragedy. A request for an emergency debate on the fire was denied by the government. John Lee admitted failures but said reforms are needed to prevent such disasters. The fire remains the key topic dominating Hong Kong society.
