The Associated Press counted at least 1,400 unique records of employees of the FBI, Secret Service, Capitol Police, U.S. Park Police and other federal agencies as well as police and sheriffs' deputies in North Carolina and Florida. The records included home addresses and phone numbers, emails and employers' names.

The FBI National Academy Associates said in a statement that the information, posted late Thursday, appears to come from the websites of three local chapters of the nonprofit, which claims nearly 17,000 members nationwide and in 174 countries.

It said it was working with federal authorities to investigate.

The group said its national database was unaffected. It said the three affected chapters were using third-party software but said it was "too early to determine if this impacted the breach."
