Chong Yun Chia, who was attached to construction firm KK Iron Engineering (KKI) at the time of the offences, was also ordered to pay a fine of S$38,174 (RM127,150) or risk an additional 38 days behind bars, the Straits Times reported.

The 40-year-old, who pleaded guilty to five graft charges on May 2, was one of four men involved in a “conspiracy to bribe” Barry Chong on four occasions in 2016.

The bribes were given to advance KKI’s business interests with the Wildlife Reserves Singapore (WRS).

WRS, which is currently known as the Mandai Wildlife Group, is the parent company of the Singapore Zoological Gardens, now known as the Singapore Zoo.

It was previously reported that Chong worked with Koh Kian Hee, To Chai Kiat and Toh Yong Soon to bribe Barry.

WRS subsequently awarded multiple contracts to KKI worth over S$1 million only to suffer an estimated loss of at least S$88,350 as a result of marked-up prices, the report said.

The court had handed down a nine-month jail sentence to To on July 2, while Toh was given a three-year and three-month jail term.

The cases involving Koh and Barry are still pending.
