The son of the former police chief of Bean Station was arraigned this morning in Hawkins County for impersonating a police officer.
His father, police chief Phillip Robinette, stepped down from his position Saturday.
This was after his son posed as a police officer while pulling over a car in Rogersville on Friday night.
21-year-old Nathaniel Ryan Robinette is charged with criminal impersonation, false imprisonment, and possession of a prohibited weapon.
Hawkins County Chief Deputy Tony Allen says authorities pulled over Robinette in Rogersville at approximately 11:00 p.m.
During a search of his car they uncovered a fully automatic assault rifle, emergency equipment and body armor.
The Bean Station Police Department is conducting its own internal investigation into this incident.
It hasn't determined whether those items were property of its department.
Nathaniel Robinette is set to appear in court next month.
He's out on a $10,000 bond.
