Man armed with knife wanted for gas station robbery.

Philadelphia police are asking for the public's help to identify a man they say pulled a knife on a gas station clerk this weekend.

The armed robbery unfolded when the suspect asked a 59-year-old clerk for help with a coffee machine at the Girard Gas Station on the 1100 block of Susquehanna Avenue Sunday night.

Police say that is when the suspect took out a knife and demanded money from the cash register.

The clerk fought back, grabbing the knife and slicing two fingers on his right hand. The extent of his injuries is not known.
