"Deputy Pat Garrett has resigned amid allegations filed in a police report today," said Lisa Marchesoni, public information officer for the Sheriff's Office, in an e-mail Wednesday evening.

Garrett worked for the Sheriff's Office for 15 years prior to his resignation.

No one was injured during the incident.

During an interview Wednesday afternoon, Sheriff Robert Arnold addressed the situation. He said Garrett had already been "decommissioned."

"The Sheriff's Office was informed Monday about allegations against Garrett," Marchesoni said. "Sgt. Nathan Pagel of the Office of Professional Responsibility opened an investigation. When Pagel called the driver of the taxi, she refused to speak with him and filed a report with the police."

Lisa Jared, who works for the Yellow Cab Company, filed a report Tuesday with the Murfreesboro Police Department. She told Officer Shondale Clark, who took her statement, that Pagel had called her about the matter before she filed the incident report.

Jared reported to police that she was dispatched to pick up a man, later identified as Garrett, while her boyfriend, Jeffrey Fryer, was "doing a ride along" with her.

"She observed two bouncers escorting a male patron to her taxi," according to the incident report. After he got into the backseat of the taxi, he could not recollect his destination for a few minutes because he "appeared intoxicated."

On the way to his destination, Garrett allegedly began playing with the back of Fryer's head.

"At this point, Fryer told him not to touch him again, when the customer identified himself as Garrett and said that he was an officer" with the Sheriff's Office, according to the report.

Fryer told Clark that Garrett proceeded to touch his shoulder, so he asked him to stop once again. He also asked the deputy to prove he was an officer by showing him his gun.

"Shortly thereafter, [he] brandished what appeared to have been a .38 caliber handgun and placed the barrel against the [left side] of Fryer's head," according to the report.

By the point, Jared told police she had reached Garrett's destination. Once stopped, she demanded he get out of the car. As he was searching for his credit card to pay for the ride, his police identification card fell out of his wallet onto Fryer's lap.

After exiting the car, Jared reported that Garrett walked to the passenger side door and demanded that Fryer slap him. However, when Garrett stepped back from the vehicle, she drove off.

MPD is investigating the allegations. As of Wednesday evening, no charges had been filed against Garrett.

The Sheriff's Office is also continuing its internal investigation into the matter.
