A man dressed much like a ninja wielded a huge knife and made off with a Wawa bag full of cash, according to the Philadelphia Police Department.

Cops said that on Dec. 15 around 3:43 a.m., a man entered the Wawa at 10550 Knights Road in far northeast Philly with a large knife demanding money. "After an employee placed an unknown amount of money inside a plastic Wawa bag, the suspect fled the store and was last seen towards a wooded area leading to Bensalem Township," authorities alleged.
