For about a year, foreman Ng Fook Meng paid the bills - of up to a few hundred dollars each month - for a mobile-phone line he did not use.
Mr Ng had been instructed by his boss to apply for the line in 2015 and to give him the iPhone and SIM card, with the foreman to be reimbursed for all charges incurred.
Mr Ng, whose name had surfaced a day before in a corruption trial involving former Ang Mo Kio Town Council general manager Wong Chee Meng, was in court yesterday to give evidence on the phone line.
The court earlier heard that an M1-registered mobile phone was given by company director Chia Sin Lan, 63, to Wong, 58, when Chia's statement to the Corrupt Practices Investigation Bureau (CPIB) was read out.
Both Chia and Wong are being tried over bribes amounting to more than $107,000, which Chia allegedly gave to Wong in almost two years. This was in exchange for advancing the business interests of Chia's companies - 19-ANC Enterprise and 19-NS2 Enterprise, which did work such as repairs and redecoration for town councils.
Both firms were awarded contracts and tenders worth millions of dollars by Ang Mo Kio Town Council during the time the alleged bribery took place, the prosecution said.
Of the 55 charges brought against Wong, one of them involves the free use of a mobile phone, with total charges of more than $2,500 incurred in 2015 and 2016.
Mr Ng said on the third day of the trial that he had been asked by Mr Tay Eng Chuan, a director with 19-NS2, to apply for the line, and he was unaware of who was using the line. Mr Ng said he eventually terminated the line after the bills showed that it was no longer being used, and that he had asked Mr Tay for permission to do so.
Mr Ng added that he has known Mr Tay for 18 to 19 years.
Earlier yesterday, Chia's lawyer Michael Loh contended that his client had been upfront about his relationship with Wong, and said the two were friends who frequented karaoke clubs and made two trips to China together.
Through the statements given to the CPIB, it did not appear that Chia was trying to distance himself from Wong, said Mr Loh, when cross-examining CPIB principal special investigator Keith Peh. Mr Peh had taken Chia's statement in October 2016.
Chia had said in his statement that he is "just friends" with Wong, who he met some time between 2005 and 2007, when Wong was working with Marine Parade Town Council.
While a handwritten ledger seized from Chia showed expenses that included charges for the use of a cellphone given to Wong, $20,000 given to Wong's mistress in China, and meals and other entertainment expenses, Mr Loh argued these did not suggest anything illegal being done as the two men were friends.
The trial is scheduled to resume in November.
