the more important question is .... how come a round was
chambered in the first place ......
unless the SPF follows diffferent procedures from the SAF
altogether .... I think someone's looking at squatting inside for
some time ..... 
Maybe one of the SPF fellas can shed some light onto this?
If it turns out that no rounds are to be chambered, then the
fella is in deeper shit than ever.
There should be three safety barriers to prevent accidental
discharge:
a). Weapon should not be cocked.
b). Even if it's cocked, the weapon should be put to safe.
c). Finger should be off the trigger.
