Based on my experience doing investigation, the ladies IC has been misused. You can report, but I doubt the lady knows what’s happening. The authorities can at best interrogate the lady and ask to whom did she shared her IC before.

Moreover, did you banked in to her bank account stated in the IC?

If that’s the case, chances are this lady:

1. Rent her account to someone else on the pretext to receive money. They are not aware of money laundering.

2. Could be someone close to her that convinced her to lend her account. Maybe relative, or BF.

Many other possibilities but this 2 reasoning is common.

Common trait is young, lady (to avoid suspicion), and deal big amount.
