Hong Kong firefighters made a final push Friday to try and find victims and any possible survivors from the city's worst fire in memory, going apartment-to-apartment in the high-rise complex in an exhaustive search.

At least 128 people were known to have died in the blaze that started Wednesday at Wang Fuk Court in the suburban Tai Po district.

Dozens more were injured, and about 900 of the 4,800 residents were evacuated to temporary shelters.

Seven of the eight 32-story towers in the building complex were engulfed in flames after construction materials and bamboo scaffolding spread the fire. Officials said extreme heat was hampering rescue efforts.

The fire was deadlier than a 1996 blaze in a commercial building in Kowloon that killed 41 people. A warehouse fire in 1948 killed 176 people, according to the South China Morning Post.

In total, 2,300 firefighters and medical personnel were involved in the operation, and 12 firefighters were among the dozens injured.

The city’s anti-corruption agency said Friday it arrested eight people involved in the towers’ renovation, including scaffolding subcontractors, directors of an engineering consultant company and project managers supervising the renovation.

Police on Thursday arrested three people, also connected to the renovation, on suspicion of manslaughter.

Hong Kong leader John Lee said the government would set up a task force to investigate the fire and the case would be submitted to the Coroner’s Court, which conducts inquiries into the causes and circumstances of certain deaths.

Lee said the government planned to inspect all housing estates undergoing major repairs to review the safety of scaffolding and construction materials.
