The bandit is considered armed and dangerous. Authorities believe he lives in the same area in which he has committed the crimes.
The second robber is called the "Doughboy Bandit" because he is rotund and wears heavy clothing.
Investigators say the Doughboy Bandit took over two Orange County banks during recent robberies.
