DO NOT PUBLISH: Ex-SCDF chief trial: 2 other companies contacted before tender of radiation devices

At least two companies were also contacted by the SCDF about radiation portals before the tender was made public in April 2011.

This emerged in court on Wednesday morning during the cross examination of SCDF director of logistics, Chin Lai Fong at the corruption trial of her former commissioner, Peter Lim Sin Pang.

One company, SECOM, which was SCDF's existing vendor was asked about the price and availability of new walk-through radiation detectors shortly after the SCDF was told by the Home Affairs Ministry to scan arriving passengers at Changi Airport, in the wake of the Fukushima nuclear disaster. Another company, IPS Securex, was asked to give a demo of its equipment.

Defence lawyer Hamidul Haq asked Col Chin if there was any wrongdoing involved by contacting the companies before the tender was put on government bidding site, GeBiz. Col Chin said no and added that she did not give the companies any details of exactly what the SCDF needed.

The prosecution has charged that Nimrod Engineering, a security systems company had received prior information from Ms Pang Chor Mui, a former general manager there, who had allegedly agreed to give Lim sexual favours in return for a business advantage.

Lim, 52, faces one charge of corruption over an illicit tryst with Ms Pang at a carpark in May 2010. She is expected to take the stand as a prosecution witness during the trial.

Before the trial started, nine other charges of corruption against Lim were stood down. They involve allegations of sex with two senior female executives. These charges will be dealt with separately.

Lim's lawyers however have maintained that the Lim and Ms Pang were just friends and had a one-time sexual encounter.
