"I think disappointment is an understatement," Rialto police Chief Mark Kling said. "It does not represent the hard-working employees that come here day in and day out."
Kling said he found out about the allegations on May 5 when one of the Spearmint Rhino employees came forward.
Four of the six officers accused of having sex while on the clock are now on paid leave.
"The bottom line is, we're going to get to the bottom of it, and if it's true, we're going to hold the people accountable," Kling said.
Kling said a priority is keeping officers accountable, and in the wake of these allegations, GPS units have been installed in every patrol car.
"As of today, that entire system in every rialto police car is up and running and functional," Kling said.
Sgt. Richard Royce, Rialto police union president, said surveillance cameras are now being installed at the union building.
"We brought that to our membership a couple of weeks ago and we were approved, and those changes are undergoing as we speak," Royse said. "I would say by the end of the month we should have all that in place."
Kling said if the accusations turn out to be true, the punishment will be swift and severe.
"If these allegations are true, having some type of sexual relationship on duty, there should be an expectation of termination," he said.
The police chief said the investigation is nearly finished and should be announced by the end of summer.
