EARLIER STORY:

West Palm Beach police are investigating an incident involving an off-duty Palm Beach County deputy from over the weekend.

It happened early Saturday morning in the 300 block of Banyan Blvd. in downtown West Palm Beach.

Cell phone video showed a man, identified by police as a PBSO deputy, holding a gun and yelling profanities at a group of men in a car, telling them to leave a parking lot.

"If I see you downtown again tonight, guess what’s going to happen?" the deputy said.

“What’s going to happen?” one of the men responded.

“Get the [EXPLETIVE] out of here now," the deputy said.

On Tuesday, West Palm Beach police confirmed they're investigating the incident involving the off-duty PBSO deputy. What police won’t confirm is what led up to the events in the video.

WPTV has been working to get surveillance video showing what happened before the men in the car started recording. We spoke with one of them who said he was inside the vehicle when the off-duty deputy approached them.

"I mean, it terrified me. I didn’t know what to do," the man, who did not want to be identified because of his safety, told WPTV. "I didn’t know how to handle the situation."

The cell phone video showed the deputy, whom WPTV is not identifying because he's not charged with any crime, tapping his gun on the car door before walking off.

Then moments later, West Palm Beach police arrived in the parking lot. Video captured by a bystander showed the deputy being questioned by police and then eventually let go.

The man inside the car told WPTV he’s just thankful the incident was caught on camera.

"What if you didn’t have that video?" WPTV's Sabirah Rayford asked him on Tuesday.

“I don’t know know how it could of turned out," he said.

West Palm Beach police said they are working with the State Attorney's Office on the investigation, but at last check, no charges have been filed.

A spokesperson for the Palm Beach County Sheriff's Office said the deputy is on paid administrative leave.
