BOULDER, Colo. — A roadside argument over a passing maneuver led a Lafayette driver to pull a handgun on a cyclist Monday afternoon, according to the Boulder County Sheriff's Office.
Roy Ragas, 52, was arrested Monday night on suspicion of felony menacing in the incident.
Cmdr. Rick Brough said Ragas is suspected of passing another vehicle in the eastbound lanes of Baseline Road near 75th Street, and coming within three or four feet of a man riding a bicycle on the westbound shoulder of Baseline.
Brough said the rider, Mark Copeland, 44, of Boulder, "motioned for Roy to move over to the side of the road."
After the driver passed the vehicle and the cyclist, Brough said, he turned around and drove next to the cyclist. A verbal argument broke out, and Ragas pulled out a handgun.
"The bicyclist is saying (Ragas) brandished a firearm and made some threats toward him," Brough said.
Ragas claims the cyclist spit at him, Brough said.
Officers were sent to Ragas' house in Lafayette Monday night on a search warrant. It wasn't immediately clear Tuesday whether a handgun was recovered, Brough said, but Ragas was arrested and booked into the Boulder County Jail.
The cyclist has not been ticketed, Brough said, and did not appear to be violating any laws while riding.
