A dozen men were arrested for trying to have sex with children over the internet as a part of a statewide investigation called 'Operation Cupid's Arrow,' authorities announced Thursday.

The North Florida Internet Crimes Against Children Task Force targeted men who have a "strong desire to have sexual relations with children," the news release said.

It was a joint operation between many local, county, state and federal law agencies. Those arrested came from all walks of life, authorities said.

Sex predators were found in online chat rooms, dating sites, classified ads and even common social media sites. Law enforcement wants parents to be mindful of what their children are doing on the internet.

Those arrested were:

Tony Sheldon of Tallahassee, Florida
Calvin McFarland of Jacksonville, Florida
Christopher Francis of Tallahassee
Darrel Harvey of Tallahassee
Michael Chmielewski of Tallahassee
William Hall of West Palm Beach, Florida
Matthew Carter of Lake Park, Georgia
Philip Graham of Live Oak, Florida
James Singletary of Jennings, Florida
Kyl Johnson of Lake City, Florida
Frantisek Pribyl of Snellville, Georgia
Dayton Michael Cramer of Tallahassee

Cramer used to be deputy general counsel for Florida State University. He resigned before the university fired him, according to the Tallahassee Democrat. He'd been earning well into the six figures and had been in his position since 2000.

He resigned via a handwritten note.

He denies the allegations against him. Cramer is married with children and has been placed under house arrest.
