DENVER -- Just a few days before Super Bowl 50, the Denver Police Department has an urgent warning.
Scammers are stepping up their game and setting their sights on Broncos fans who might be desperate to find tickets to the game Sunday.
One seller on Craigslist used the same fake tickets at least twice to scam buyers out of several thousand dollars.
One man in Denver answered the ad and agreed to pay $6,000 for both tickets only to receive an envelope with blank pieces of paper inside.
"But I honestly thought, yeah, the tickets are going to be real. There's nobody that would go through these lengths knowing that the purchase is protected," Cody Sudmeier said.
Sudmeier was smart enough to pay for the tickets with PayPal Protected. He will be able to get his money back after PayPal investigates.
Denver police have tracked the scammer to a man in Kansas.AlertMe
