A caller ordering pizza from a Southern California pizzeria overheard an armed robber demanding money and promptly called the police.

Palm Springs police Officer Rhonda Long says the customer was placing the phone order Tuesday evening and heard the commotion at the Pizza Hut. The officer says the caller heard the suspect demanding money, so he notified police.

A masked man with a handgun took money from the cash register and fled.

Long told the Palm Springs Desert Sun that the robber didn't take money from any customers. So far, there hasn't been an arrest.
