Organised robbery groups spend a lot of time planning bank heists. They watch a bank for days or weeks.

These groups study how money moves in and out of the bank. They also look at security measures and how they can escape after the robbery.

This information comes from fraud prevention expert Richard Kumadoe. He gave this warning about how criminals operate.

Kumadoe said that criminals are now doing their own risk assessments. They identify weak spots in and around banks.

This careful planning helps them succeed in their crimes. They choose targets based on these assessments.

Banks and other financial institutions need to be aware of these tactics. They must strengthen their security to prevent such attacks.
