A man is arrested for impersonating an FBI agent.

Bixby police said he did it while in a school pickup line at Bixby East Elementary.

The arrest affidavit for Michael Williams said a woman told police that Williams asked her to move her car and showed her a badge that said FBI on it.

She said Williams told her that he would "get her" after she asked if she could take a photo of it.

FBI agents searched Williams' home on a warrant a few days later and found a semi-automatic rifle and ammunition.

The affidavit said agents also found an emergency light bar, handcuffs and a dash camera inside his jeep.

Those documents also reveal that investigators learned Williams is a felon. He was convicted in 2003 for a robbery out of Florida and has a 2009 firearm conviction out of Texas.

Contact the FBI Tulsa office at 918-664-3300 if you have more information about Williams to provide to authorities.
