WATCH: King County Detective Draws Gun On Unarmed Motorist During Traffic Stop

A veteran detective of King County, Washington, was placed on administrative leave after a video of him drawing a gun on a motorcyclist during a traffic stop surfaced Monday.

Alex Randall, a motorcyclist from Shoreline, Washington, posted a video of his encounter with the detective on Aug. 16, near the Seattle-Shoreline city line, on YouTube.

In the video captured on a GoPro camera attached to his helmet, Randall can be seen riding his bike and coming to a stop behind other vehicles at a red traffic light. The police officer seen in plain clothes then walks up to him and points a gun.

In the introduction to the video on his channel Squid Tips, Randall wrote about the officer: “He does not show a badge, provide a name, or give me a citation. On review of the video, a badge could be seen and a license plate recorded.”

After pulling Randall over, the officer who has not been named asks him: “How ya’ doing?” to which the rider curses and says: “What are you doing to me?”

The detective can be heard replying: “What do you mean what am I doing. You’re f****** driving reckless. Give me your driver’s license or I’m going to knock you off this bike.”

The rider then repeatedly assures the police that he is unarmed and that he will pull over, while the detective asks the rider for identification (ID) and says he will “dump” the bike of Randall attempts to move it. The officer then takes the motorist’s wallet from his pocket.

Randall asks for permission to move the bike off the roadway, turn it off or take off his helmet as he could not hear anything through it. “I’m sorry. You have a gun drawn on me, so I’m a little panicked,” he can be heard saying.

“Yeah, you’re right, because I’m the police,” the deputy says in the exchange. “That’s right. When you’re driving and you’re going to place people at risk at 100 mph-plus on the god-dang roadway.” However, Randall told reporters that he did not get a ticket for reckless driving.

After looking at Randall’s ID, the detective puts his gun away and tells the rider that reckless driving is “an arrestable offense,” and allows the rider to pull his bike over.

At the end of the video, however, Randall says in text: “The statement that I was going 100+ miles an hour is fabrication and exaggeration.” He added that the officer was using his authority to simply scare and lecture him.

King County Sheriff John Urquhart called the video “very troubling” and told Q13 News that it had come to his attention 5 p.m. EDT Monday.

"I haven't heard the other side of the story, but I don't like what I see," the sheriff said. "There's nothing standard about approaching a driver with a pistol out. That should not have happened."

In a Facebook post, Urquhart said: “ In every encounter I expect my deputies to treat others with respect.” Randall in a Twitter post said the sheriff had called him personally to apologize and promised an investigation into the incident.
