The Independent Commission Against Corruption (ICAC) said it arrested eight people on Friday in connection with the Wang Fuk Court fire that killed at least 128 people.

The ICAC earlier opened an investigation into the fire at the Tai Po residential complex, which was under a large-scale renovation.

It said the group of seven men and one woman arrested were aged between 40 and 63, and included "four individuals from the consulting firm of the grand renovation project of Wang Fuk Court, namely two directors and two project managers responsible for supervising the project".

The others arrested included three scaffolding subcontractors and a middleman.

ICAC investigators also seized work documents and bank records from 13 premises.

On Thursday, the police said they had arrested three men on suspicion of manslaughter as part of their investigations.
