The announcement come days after the woman at the center of the sex scandal, Nancy Holtgreve, filed a $500,000 civil rights lawsuit against the city.
Holtgreve spoke the KTLA during an exclusive interview this week.
She says she is living in fear. "You know, I'm scared, and what can I do? Nothing."
Holtgreve is a bartender at Spearmint Rhino Gentlmen's club in Rialto and says that's where she met former Rialto police officer James Dobbs, the father of her son Carson.
Looking back on how the sexual relationship started, she says many Rialto police officers would visit the club while on duty, wearing their uniforms and take her and other Spearmint Rhino employees inside buildings connected to the department, such as the Police Benefit Association Union Hall, where they would have sex.
Holtgreve says she became pregnant after one of the encounters and says her son's father is Dobbs and she has DNA tests to prove it.
After Holtgreve gave birth, Holtgreve says she asked Dobbs to extend his medical insurance to their son and that's when Dobbs' attitude changed.
"It started off very gradual with the verbal abuse. And then the physical abuse started," says Holtgreve.
"On one occasion when Carson was -- not a foot away from me, sleeping in his bassinet, he physically pushed me up against a wall... he's a cop, what am I going to do about it, don't f- with him. I don't think you can fully understand it unless you're actually with an officer that's terrorizing you."
After the accusations surfaced, Rialto Police Chief Mark Kling says they conducted an extensive four-month internal affairs investigation and confirmed Holtgreve's claims of late-night sex-capades with department officers.
"We know that Miss Holtgreve met secretly on several occasions with a number of my employees. And where they met was at the Rialto Police Benefit Association," says Kling.
He adds, "The officers would meet her there. They would engage in consensual sex. Most of these cases occurred off duty."
In the wake of the scandal, Kling says four current officers have been disciplined and two officers, including Dobbs, have left the department.
"Fortunately for the Rialto Police Department and this community -- James Dobbs is no longer a member of this police department. He resigned that position in late August," says Kling.
When asked what he thought about the situation, Kling said, "I was appalled. And people can rest assured that I'm angry. This is not representative of professional law enforcement, but it doesn't represent this department."
Moving forward, Kling promises zero tolerance for any 'bad seeds" in the department.
Meantime, Nancy Holtgreve filed a $500,000 lawsuit againt the City of Rialto and Rialto police and hopes it will send a clear message, saying, "I hope something good comes out of it."
Dobbs has since moved out of Southern California and as of our deadline, he has not responded to our efforts to speak with him.
Rialto Police Chief Kling told us that as a safeguard against future police misconduct, the department has installed automatic vehicle locators in all of their police cars, giving real-time information to supervisors about the location of every officer on the force.
