Boston Police report  that when officers responded to the Citizens Bank branch at 77 Franklin St. for a possible robbery this afternoon, they found a man being held down by other people.
Police say Dana Werrick, 50, of South Boston, entered the bank around 1:30, told a teller he had a gun and demanded $300. A man at a neighboring teller station heard that, police say:
The male witness stated that at that point he jumped on the suspect and a fight ensued. The witness was able to subdue the suspect and hold him until officers arrived.
Police say officers did not find a gun but that because he said he had one, Werrick was charged with armed bank robbery.
