A security guard who police say pulled a woman over and insisted she pay $20 to get out of a speeding ticket has been charged with impersonating a public servant, a third-degree felony.

Officers in Crowley arrested Raimond Jett Nutz, 24, on Thursday on a warrant issued July 11. He has since been released from the Tarrant County jail after posting a $2,500 bond.

A woman told Grapevine police that a man pulled her over just before 2 a.m. June 26, claiming she had been driving 5 mph over the speed limit but could avoid a ticket if she paid him $20.

He wore an ill-fitting uniform without a badge or gun, and had flashing lights on the dashboard of his unmarked white Ford Crown Victoria, she said. Doubting his identity, she drove off from the 2000 block of State Highway 26 and called police.

Authorities identified Nutz as a suspect after learning from his employer that he'd been working in Grapevine as a security officer that night, police spokeswoman Amanda McNew said. The woman identified him from a photo lineup, police said.

"We applaud the victim for trusting her instincts, getting out of this potentially dangerous situation, and immediately reporting the incident to police," the department posted on Facebook. "Anyone who is stopped by an officer and feels something is wrong should call 911."
