JACKSONVILLE, Fla. -- Many of the people wrapped up in the Operation Reveal the Deal investigation worked for the Fraternal Order of Police while working a side job for Allied Veterans of the World.

Jacksonville Sheriff John Rutherford said anything done by a Jacksonville Sheriff's Officer or employee outside of their regular job, such as opening a business like an internet cafe, has to go through the Office of Secondary Employment at JSO.

According to that rule, FOP officers Nelson Cuba and Robbie Frietas should have made the Sheriff's Office aware of their plans to go into business. Cuba and Frietas were arrested in connection with the investigation Tuesday.

Often JSO officers are hired for extra work, for example by a private company to provide security for an event, or work a party. They are assigned extra hours outside their regular shifts to work traffic detail at big events like a football game.

They must complete a secondary employment form to be assigned or receive permission.

"That is so that we can keep track of what our officers are involved in, and we can make sure there is no conflict of interest, not working for something that would create a conflict for the agency," Rutherford said.

Cuba and Frietas did no such thing, Rutherford said.

"All these shell companies they were involved in they should have made us aware of, obviously they did not. They were involved in a criminal enterprise, it doesn't surprise me that they did not tell me about it through a secondary employment form," Rutherford said.

Rutherford said when they became aware of improprieties, they investigated Cuba and Frietas for two-and-half years. Rutherford said he was proud of the fact the many people in his agency working on the case kept it quiet and never leaked it to the targets.

"It was officers wearing that JSO badge that went after two high profile officers wearing that JSO badge. We followed the evidence to where ever and whoever it touched and we went after them."

Rutherford told members of the Tiger Bay Club on Friday that this investigation was one of the most difficult times of his life -- tough knowing what he knew and where it was going.
