A man armed with a handgun and with his face hidden by a plastic mask robbed a Herndon PNC Bank, Fairfax County police said.

Police said they did not have surveillance pictures of the Wednesday robbery, in which the man put the gun in the faces of two female tellers and demanded cash. The women complied and he quickly departed the bank with an undisclosed amount of cash. Outside, police said the suspect jumped into a newer-model, silver- or gray-colored Nissan sedan and drove away.
