The incident unfolded at about 2:20 a.m. Sunday on Capitol Hill when two men got into a verbal altercation over a traffic or parking dispute near 14th Avenue and East Marion Street, said Detective Mark Jamieson.
As one of the men was on his cell phone, the other attempted to grab the cell phone out of the victim's hand. When that was not successful, the suspect went to his car and pulled up next to the victim, pointing a handgun at him.
The victim told the suspect he was on the phone with 911. The suspect then left the area.
Police were notified and found the suspect driving in his vehicle at James Street and Interstate 5. The car was stopped and the suspect was taken into custody, Jamieson said.
The suspect told officers there was a gun inside the car and gave officers permission to search the car. A loaded .45 caliber handgun was recovered.
The 43-year-old suspect was booked into the King County Jail.
