The US Secret Service has been investigating two Mid-State high school students in a counterfeit money case.
The two have already been placed under arrest and charged with passing counterfeit money at school.
Those with the Metro Nashville Police Department said two McGavock High School students -- a 17-year-old and a 16-year-old -- were arrested at the school and charged with criminal simulation.
They have been accused of passing at least one counterfeit $20 bill at their own school, which made the case unique.
Most counterfeit bills have been passed off by adults at businesses.
For instance, realistic looking "teller training notes" used to train bank employees have shown up before, as well as Hollywood money.
"[Hollywood money] says 'for motion picture use only' just across the top and on the back 'for motion picture use only,'" said a police investigator.
In recent months, bogus Hollywood prop money was spent in Woodbury, Lebanon, and Murfreesboro.
Police said anyone who has spotted a counterfeit bill should keep it and report it.
"If you don't take it out of the system, if you give it back to them, they'll likely find another victim to pawn it off on," said Sergeant Kyle Evans with the Murfreesboro Police Department.
It was not clear what type of counterfeit bill was passed at McGavock High School, but the victim noticed and turned it over to the School Resource Officer.
Now the Secret Service has gotten involved.
Police said they believe the two teen suspects knew the bill was fake, but it was not clear if they made it or obtained it.
The two have also been potentially facing federal charges, not to mention discipline from the school.
For now the focus has just been on the one counterfeit bill, but part of the ongoing Secret Service investigation will be looking into whether there were others.
While counterfeit cases in general have not been unusual, this was one of the Mid-State's first reported cases of bogus bills allegedly being passed at a school during classes.
