WINTER PARK, Fla. -

The bystander who Winter Park police say helped a woman who was being attacked by her estranged husband and had a gun pulled on her spoke out on Tuesday.

Police said Robert Potchen, 57, and his estranged wife got into an argument after 5 p.m. Monday in the parking lot of an office complex at Wymore Road and Fairbanks Avenue when he pulled out a gun and attempted to force her into his pickup truck.

Jamie Koczar said he heard the woman scream and came outside of his office, saw what happened and went to help the woman, bringing her into one of the office buildings in the complex.

"I look over and I see him come around the corner of the truck with the gun raised pointed at my head. I could see right down the barrel," Koczar said, adding that he started to shake as he ran from Potchen. "I was backing her away from the truck as he was coming toward me. We ended up over in some of the brush in front of the parked cars. Trying to put whatever we can between us and the man. "

Koczar dragged the woman into a nearby office to get her away from Potchen and another employee locked the front door. Police said Potchen followed them and attempted to break the glass of the front door with his gun, which shattered the glass.

Koczar said Potchen didn't shoot as he claimed, but eventually gave up. Police said Potchen then stole a cellphone.

No injuries were reported in the incident.

Potchen turned himself into authorities early Tuesday morning and was booked into jail on charges of kidnapping with intent to harm, robbery with a firearm, battery, aggravated assault, armed burglary. He is being held on no bond.
