Hong Kong police arrested the bosses of a construction company on suspicion of manslaughter on Thursday over the city's worst fire in nearly 80 years, which killed at least 83 people with scores more listed as missing, Reuters reported.

By the early hours of Friday, firefighters had mostly contained the blaze raging for more than 24 hours, ripping through the Wang Fuk Court housing complex in the northern district of Tai Po. The estate had been undergoing renovations and was wrapped in bamboo scaffolding and green mesh.

Most of the victims were found in two high-rise blocks in the eight-tower complex, Deputy Director of Fire Services Derek Armstrong Chan said, according to Reuters.
