Police in Philadelphia in the US state of Pennsylvania say they are looking for a man who robbed a convenience store by using a banana in his pocket to simulate a gun. The surveillance video shows the suspect stealing a banana from the counter by the cash register while waiting in line. He then placed the banana in his front pocket of his hooded sweatshirt and pointed it toward the cashier. Saying he had a gun, the man demanded cash and cigarettes before riding off on his bike. According to police, the banana gunman is still at large.
