Hong Kong officials said Monday that their investigation into a deadly blaze that killed at least 151 has revealed netting that covered scaffolding used in renovations was not up to fire-safety codes, as a wave of public sympathy and support was met by government moves to stifle criticism.

Wednesday’s blaze, which took until Friday to fully extinguish, started on the lower-level netting around one building in the Wang Fuk Court complex. It then swept inside as the foam panels caught fire and blew out windows. Winds carried flames from building to building. Soon, seven of the eight apartment towers were ablaze.

Initial tests of the netting showed it was up to code, but subsequently investigators collected 20 samples from all areas, including higher floors, and found seven failed safety standards, suggesting contractors skimped to make greater profits, said Eric Chan, Hong Kong’s Chief Secretary.

“They just wanted to make money at the expense of people’s lives,” he told reporters.

Chris Tang, Hong Kong’s Secretary for Security, said investigators initially hadn’t been able to reach certain areas, which led to the new findings.

“Because the fire is now out, we have been able to get to places that were not easily accessible before to take samples,”

Donations for survivors of the fire had reached 900 million Hong Kong dollars (US$115 million) as of Monday, authorities said, as a steady stream of people placed flowers, cards and other tributes at a makeshift memorial near the burned-out block of buildings.

“When something happens, we come out to help each other,” said Loretta Loh, after paying her respects at the site. “I have a heavy heart.”

Some 4,600 people lived in the Wang Fuk Court complex in the suburb of Tai Po.

Hong Kong police Disaster Victim Identification Unit staff went through five of the burned buildings but only made partial progress through the remaining two, said Tsang Shuk-yin, head of Hong Kong police’s casualty enquiry unit. Teams were assessing the safety of the other buildings, including the one that caught fire first and suffered the worst damage.

On Monday, they recovered another eight bodies, including three firefighters found earlier but couldn’t retrieve. Dozens of people remain unaccounted for, but some are likely among the 39 bodies not yet identified, Tsang said.

“We will have to wait until we get through all seven blocks before we can make a final report,” she said.

The donations and 300 million Hong Kong dollars (£38.5 million) in start-up capital from the government will be used to help victims rebuild their homes and provide long-term support, local officials said. The government has also given survivors cash subsidies to help with expenses, including funerals, and is working to find them housing.

By Monday, 683 residents had found places in local hotels and hostels, and another 1,144 moved into transitional housing units. Two emergency shelters remained open for others, authorities said.

The complex’s buildings were all clad in bamboo scaffolding draped with nylon netting for external renovations. Windows were covered with polystyrene panels.

Residents had complained for almost a year about the netting, Hong Kong’s Labour Department said. It confirmed officials had carried out 16 inspections of the renovation project since July 2024 and had warned contractors multiple times in writing that they had to meet fire safety requirements. The latest inspection was just a week before the fire.

Hong Kong’s anti-corruption agency has arrested 11 people, including the directors and an engineering consultant of a construction company. A growing number of people have been questioning whether government officials should also be held responsible.

“People are angry and think that the HK (Hong Kong) government should be accountable,” said Jean-Pierre Cabestan, a locally-based political scientist and senior research fellow at the Paris-based Asia Centre think tank.

But the leeway for dissent is limited in the former British colony, which came under Chinese control in 1997 and increasingly has moved to quiet public criticism on national security grounds.

“There are rumours being spread by bad people giving fake news about the firefighters not employing the correct tactics to fight the fire, or victims being charged 8,000 Hong Kong dollars a night to stay in hotels – these are all false,” Tang said.

“We will arrest these rumour mongers.”

On Saturday, the Office for Safeguarding National Security blasted what it called “evil schemes” that had “the ulterior motives of using the disaster to create trouble and disrupt Hong Kong.” It did not give specifics.

On Saturday, a man who helped organise an online petition calling for government accountability was arrested on suspicion of sedition, local media including HK01 and Sing Tao Daily reported. Two others were arrested on Sunday, including a volunteer who offered help in Tai Po after the fire broke out, the same outlets reported.

Cabestan said Hong Kong officials were operating like authorities in mainland China, forestalling protests before they might develop.

Police would not comment specifically on the arrests, telling The Associated Press only that “police will take actions according to actual circumstances and in accordance with the law.”

Dissent in the city has been muzzled since hundreds of thousands took to the streets in 2019 against government plans to allow extradition to mainland China. Hong Kong now virtually bans mass protests and bars opposition political figures from running in legislature elections.
