Authorities say a man tried to rob a car wash in Northern California with an empty potato chip bag and an alleged handgun.
Rohnert Park's Department of Public Safety says in a statement the man dropped an empty potato chip bag on the counter and told the cashier to fill it with money and warned her he was armed with a gun.
The department says the man gestured that the weapon was in the empty bag but the casher saw the bag held only a piece of cardboard and called a co-worker for help.
Officials say that when the other employee approached the suspect, he fled on foot.
Police say he was wearing a black baseball hat, dark pants and a black sweatshirt over a white t-shirt when he entered the KaCees World of Water car wash Friday night. He also was unshaven and had grey facial stubble.
