JACKSONVILLE, Fla. -- Escalating tensions between Jacksonville prosecutors and police have led to an internal investigation at the sheriff's office.

An assistant state attorney recently filed a formal complaint about a run-in with a police officer that she described as frightening.

Earlier this week, Sheriff John Rutherford blasted State Attorney Harry Shorstein, saying the state attorney's office dropped the ball on a gun case, putting his officers in danger.

The issue began when Vernon Pandy was arrested and charged with a felony for carrying a concealed weapon. On July 7, Pandy's charge was reduced by the state attorney's office to a misdemeanor after the office received a call from former Jaguar Tony Boselli on Pandy's behalf.

The officer who arrested Pandy, Jason Lederman, said he was never informed about the change and questioned assistant state attorney London Hairston about why it happen and why he was not kept in the loop.

Hairston has filed a complaint against the officer.

Channel 4 was told the conversation between Hairston and Lederman became very heated; however, the head of the police union said it was civil.

"(He) told her he was displeased. He said, 'Yes, I did raise my voice, but at no time was it to the point that there was anything unprofessional said. But, I was very displeased with the way this was done and why they did it because it was my life being risked out there,'" said Fraternal Order of Police President Nelson Cuba.

Hairston told Channel 4 a different story about what happened. She said she felt very threatened and had never been treated like that before. That's why she filed the complaint.

"So she had 12 days that if she wanted to file a complaint and she was so intimated or scared or whatever she was saying of Officer Lederman, she could have done that in the meantime. She didn't do it until after this letter came out," Cuba said.

However, Hairston said, "I did have a meeting the day after the incident."

She said the issue would be over if Lederman or Cuba would apologize.

"Someone needs to take responsibility," Hairston said.

A check of the Lederman background revealed 19 complaints from citizens about the officer ranging from rudeness to conduct unbecoming of an officer. All of those were dismissed.

Lederman also has had several internal complaints that involve improper action and interfering with an investigation.

The latest complaint filed by Hairston remains under investigation.
