The FBI needs your help catching the brazen thief who robbed a bank on his bike.

The man has been dubbed the BMX Bandit.

The FBI gave him the name because of the child-sized bike he rode away on.

This happened at the Amegy Bank on Highway 6 in Missouri City Tuesday.

Investigators say the man walked in and pulled out a gun and demanded money.

Security cameras caught him riding away on the bike.

If you recognize the man, you're asked to call the Missouri City Police Department.
