Will key witness Cecilia Sue end up being charged?
Key prosecution witness Cecilia Sue left the witness stand on Tuesday after four days of testifying in the case against former anti-narcotics chief Ng Boon Gay.
But her testimony left many wondering what lies ahead for the former IT sales manager who told graft investigators that she had a long-running sexual relationship with Ng, only to deny it all in court.
Prosecutors and defence counsel have both accused her of lying - either in court or to the Corrupt Practices Investigation Bureau (CPIB), which recorded at least 10 statements from her.
This raises the question of whether she may end up being charged with an offence herself.
Even if there is no actual interference with government procurement approval processes on account of the illicit gratification, the prosecution said, 'the fact that the gratification was so obtained is cause for great concern and can amount to criminal behaviour'.
