The burglary happened at a business in the 83000 block of Utica Avenue. The incident happened on a Saturday night in August.
Surveillance cameras captured video of the suspects as they broke into the place. In the footage, the men realize there is a surveillance camera, and then they try to cover their faces before one man disables the camera.
Police say the men took a large amount of cash, gold and silver bars, along with a personal humidor signed by Arnold Schwarzenegger.
