The robberies happened at a Chase branch in May and July, and then again at a Banco Popular on Sept. 7. In the robberies, Platis allegedly handed notes to the tellers, threatening that he had a weapon.
The FBI dubbed him the "Balding Bandit" because of his apparent receding hairline.
Platis is scheduled to be arraigned Wednesday at Downey Courthouse
