The death toll from the deadly blaze at Wang Fuk Court in Tai Po has climbed to 146 after 18 more bodies were found on Sunday, according to the police.

Most of the bodies were recovered in Wang Tai House -- one of the two most severely damaged blocks in the eight-tower residential complex. They were found inside apartments and on staircases and rooftops. The police did not rule out the possibility of finding more victims.

The conditions inside the fire-ravaged blocks are extremely poor, with the interiors completely charred and no electricity for lighting, said Cheng Ka-chun, head of the police’s Disaster Victims Identification Unit which is searching the blocks for bodies.

He said the lighting inside is too poor for the operation even in day time, and officers have to rely on headlamps and portable lights despite being armed with illumination devices provided by the Chinese mainland.

Officers had completed searching in two more towers by Sunday, leaving just three more to finish the search in the estate’s seven affected blocks.

“Even during the day time, it’s very difficult to see in areas away from the windows. We have to go all out and conduct the search during the day to be most efficient,” Cheng said,

Conditions outside the blocks were also not ideal, littered with many fallen objects like bamboo and air conditioners, some of them with thorny debris.

The search in Wang Shing House has been ongoing, and will later move to Wang Sun House. Wang Chi House -- the only block that was left unscathed in the fifth-alarm inferno – will remain closed due to the building’s poor condition with objects left dangling on the higher floors, posing safety risks for residents.
