UPDATE 9/18/17 @ 10:35 a.m.

KANAWHA COUNTY, W.Va. (WSAZ) -- A Nitro police officer caught on camera in an off-duty incident involving a gun has been been terminated from the police force.

Chief Bobby Eggleton tells WSAZ Richard Foster was served a letter of termination last week after the completion of an internal investigation.

A video originally posted to Facebook shows Foster, who appears to be off duty, holding a gun while he's exchanging words with two different men.

"I regret that I have been forced to make this decision," Chief Eggleton said.

Foster turned himself in to police on a brandishing warrant after the incident.

A court hearing is scheduled for November for that charge.

"I and the public expect officers of the law to act in a professional manner at all times," Chief Eggleton said.

ORIGINAL STORY 7/14/17

KANAWHA COUNTY, W.Va. (WSAZ) -- A Nitro police officer is facing charges following an incident caught on camera involving a gun.

Richard Foster, 49, of South Charleston, turned himself in to police on a brandishing warrant.

A video originally posted to Facebook shows Captain Richard Foster, who appears to be off duty, holding a gun while he's exchanging words with two different men.

Nitro Police Chief Bobby Eggleton released a statement saying, "Capt Richard Foster has been placed on administrative leave until further notice. He has been relieved of his police weapons, vehicle and police identification. This is an ongoing internal investigation by the Nitro Police Department and a criminal investigation by the Kanawha County Sheriffs Office."

The Sheriff's Office says they are in the process of interviewing witnesses.

The person who took the video tells WSAZ the argument started because a group of people were trying to move a trailer onto a property that neighbors Capt. Foster's family.

According to the person taking the video, Foster's mother was blocking the way and asking to see the permits for the move.

When someone told her to get out of the way, she got her son involved.

WSAZ has reached out to the Foster family for comment but our messages haven't been returned.
