A devastating fire ripped through the Wang Fuk Court complex in Tai Po on November 26, claiming at least 55 lives and leaving hundreds missing after spreading via renovation scaffolding.

Considered one of Hong Kong deadliest fire in decades, it spread so fast that several buildings were caught in the blaze. The complex had eight buildings with nearly 2,000 apartments.

Firefighters have been fighting to control the flames since midafternoon Wednesday, when the fire started, and then spread across seven of the complex’s eight buildings.

Fires in four buildings had been effectively put out, with the remaining three towers under control, authorities said on Thursday. They said the operation could last until the evening.

Firefighters fought the blaze for over 24 hours, with three men from a construction firm arrested on suspicion of manslaughter.

The Tai Po fire has now been declared Level-5, which is the most serious fire category in Hong Kong.
