Authorities in Hong Kong have arrested 13 people on suspicion of manslaughter related to last week’s deadly fire at the Wang Fuk Court estate in Tai Po. The fire, the city’s worst in 75 years, has claimed 151 lives, with around 40 people still missing. Emergency services are continuing to search the seven towers. The estate, housing almost 5,000 residents, was being renovated before the fire. These renovations are linked to the cause. Angry residents say past safety violations by the construction company and weak enforcement allowed the disaster. Hong Kong’s anti-corruption agency said it arrested directors and an engineering consultant from the construction firm. They have started a full manslaughter investigation. Chief Secretary Eric Chan revealed that seven out of 20 tested samples of scaffolding mesh netting failed fire safety standards. He called the use of cheaper, noncompliant netting a “shameful act” done to avoid detection. "They just wanted to make money at the expense of people’s lives,” he said. At the same time, police have detained two civilians under national security laws. One, student Miles Kwan, was arrested over an online petition demanding support for victims and accountability for officials. Local media said Kwan’s arrest was for "seditious intention." Kwan stated he was only asking for basic demands. Another civilian, former district councillor Kenneth Cheung, was also arrested. Secretary of Security Chris Tang justified the arrests by citing the need to counter threats to national security but gave no detailed explanation. Public reaction on social media criticized these arrests during a time of mourning. Some comments compared Hong Kong’s approach to China's strict stance on dissent. Others worried that these moves would silence public questions about governance. These arrests come after national security officials warned they would crack down on anyone stirring "anti-China" sentiment from the tragedy. Though volunteer support for victims surged, officials soon stepped in with armed police patrols and took over organization. The petition by Kwan echoed protest movement language but did not seek political change. He expressed concern that basic calls for accountability were being labeled seditious. The situation highlights growing tensions as Hong Kong deals with the aftermath of this tragic fire.
