The Independent Commission Against Corruption has arrested 11 people alleged to have accepted bribes relating to a project aimed at preventing landslides.

A site agent and site engineer from the construction engineering company to whom the Civil Engineering & Development Department had awarded the project were among those arrested.

The others included seven subcontractors and two other individuals.

The ICAC investigated after receiving a complaint alleging some construction engineering company staff might have accepted advantages from subcontractors for favouring them.

Project's contracts valued at $74m

The construction engineering company was awarded the landslip preventive-measures project for slopes in different districts in 2004. The project's contracts - valued at $74 million - were then subcontracted out.

ICAC enquiries suggested the arrested site agent and site engineer had allegedly accepted bribes totalling $410,000 from the subcontractors.

In return, the two men allegedly showed those subcontractors favour in awarding the contracts, and recommended the early release of  payments to them.

Enquiries are continuing.
