LAS VEGAS >> Las Vegas cab driver Gerardo Gamboa thought someone left a bag of chocolates in the back seat.

But this stash turned out to be cold hard cash.

The Las Vegas Review-Journal reports Gamboa was making a pickup Monday at the Bellagio when a hotel doorman noticed the brown paper bag and handed it to him.

At a red light the Checker Cab driver’s curiosity got the best of him. To his surprise, he found six bundles of $100 bills totaling $300,000.

The newspaper reports Gamboa called his dispatcher and took the money to the company’s main office.

Las Vegas police and casino officials were able to link the money to a well-known poker player they declined to identify.

It is unknown whether Gamboa will receive a big Christmas tip.
