An officer from the Immigration and Checkpoints Authority (ICA) was charged on Tuesday with three counts of forgery.
Mohammad Rahimi Hussain, 24, is believed to have doctored three medical certificates in a flat at Block 750, Woodlands Avenue 4, in August and September last year.
Each of the three documents he allegedly forged originally stated that he had been given a day's leave.
It's believed that Mohammad Rahimi inflated the rest period the doctors had given him to up to four days.
He will be back in court on March 29.
If convicted of forgery, he could be jailed up to four years, fined or both on each charge.
