SCHENECTADY, NY (WRGB)--In a letter to the casino obtained by CBS 6, the New York State Gaming Commission fined Rivers $6,000 after an underage gambler won a jackpot on the gaming floor February 14th.

Investigators say they found the security officer at a checkpoint disregarded an ID scanner that raised a red flag when Andrick Singh, 20, visited the casino.

The legal gambling age is 21 for commercial casinos.

Authorities say Singh was on the gaming floor for an hour and 45 minutes.

They also wrote casino personnel admitted to knowing the officer 'was unqualified for the position and lacked sufficient training."

A representative with the Gaming Commission tells CBS 6 fines like this aren't uncommon. They added staffers acted appropriately after Singh hit a jackpot and won some $1,326 at the casino.

A casino spokesman said in part -

"Rivers Casino & Resort acted swiftly and appropriately once the underage customer was identified, and also self-reported this incident to the New York State Gaming Commission. Responsible gaming, including preventing underage gaming, is a top priority at our property, and we are continually making improvements to our operations to maintain our commitment to that mission. That is why we are glad to be partnering with the New York Responsible Play Partnership to present today's public meeting on Responsible Gaming."

Rivers hasn't been hit with any other fines. They're reviewing the state's findings and still have a couple of weeks to respond—and potentially appeal.
