No matter how many times the money is transferred, the electronic trail will be recorded until the money is cashed out.
Even if the money is cashed out ,the person identity will be known because he owns the final bank account.

It is up to OCBC and the police to go after the person who cash out the money.

No one can steal bank money using online account without exposing their own identity

Maybe still under investigation. But surely someone can come out and address this and take full responsibility. That will give public confidence.
