This from the Bank Terrorism blog:

At 9:38 AM on Wednesday, October 15, 2008, three black males entered the Citibank Mall of Orange Branch in Orange, CA with drawn handguns and executed a takeover robbery. The suspects ordered customers and personnel to the floor, stole a large sum of cash from a customer who was at the bank to open an account, took cash from two tellers and then forced bank personnel into the bank’s vault. A Personal Banker was accosted by one suspect who ripped the employee’s wrist watch from his arm. No other injuries were sustained. It is believed that there was a fourth individual involved in this robbery who stood by in what is believed to be a light colored Toyota Corolla. There is no known description of this drive.
 
The suspects are described as two thin black males wearing hooded sweatshirts and another black male wearing a “bucket hat” (see photo on left) who was considered as being more muscular. All had handguns, but the guns were not readily identifiable. The robbery lasted approximately four minutes. There were no injuries to any of Citibank’s customers or personnel. The bank did not reopen for business.
