Florida Attorney General Pam Bondi's office has received at least four complaints about Police Protective Fund since 2010.
A retired police officer in Maryland asked regulators to investigate the organization after he was solicited. A North Carolina woman complained that Police Protective Fund had fraudulently obtained her 95-year-old mother's personal information and charged her credit card.
The Attorney General's Office took no action and did not pass the allegations on to the Agriculture Department, which regulates charities.
State officials on Tuesday arrested Jason Robert Williams, who is on probation for sexual battery. Williams, 33, of Holiday, is the manager of a one of the Port Richey phone rooms.
His 60-year-old father, James Paul Williams Jr., was also arrested. Williams, of Tarpon Springs, oversees all five of the charity's Florida phone rooms.
Also arrested were Phillip Brian Stinson, 31, manager of the charity's New Port Richey call center and Jose Ramon Quinones, 49, who manages its phone room in Davie.
None of the men could be reached for comment.
The charge, a third-degree felony, carries a fine of $500 for each violation.
Three years ago, Florida regulators visited one of the Port Richey call centers and found that at least five employees had been convicted of fraud, theft or armed robbery.
At the time, James Williams told investigators that the charity couldn't afford to do background checks and had to rely on employees to voluntarily disclose their criminal histories, according to a Pasco County sheriff's report.
The state closed the case with a warning, saying future violations would be a third-degree felony.
Adam Putnam, who became Florida's agriculture commissioner in 2011, recently proposed strengthening charity oversight in response to the Times/CIR investigation into America's worst charities. Among his proposals is making background checks mandatory for charitable solicitors.
"Charities that cannot follow state law cannot be trusted with Floridians' hard-earned money," Putnam said Tuesday. "By cracking down on charities that hire felons, we're working to make sure more of Floridians' charitable contributions are used to do good."
