ST. JAMES PARISH- Authorities arrested a man they say was impersonating a Louisiana State Trooper.

State troopers were contacted by the St. James Parish Sheriff's Office Nov. 28 to assist with the investigation. The person impersonating a trooper was identified as 37-year-old Thomas Mansur.

Authorities say the initial investigation began around 11 p.m. Tuesday night when a St. James Parish Sheriff's Deputy was conducting patrols at the St. James Boat Club on US Highway 61. During his patrols, the deputy noticed two vehicles without boats or trailers in the parking lot.

According to authorities, the deputy noticed a male and female sitting inside one of the vehicles as he approached. As the deputy attempted to determine their reason for being in the parking lot, Mansur identified himself as a state trooper and presented a Louisiana State Police Sergeant's badge to the deputy.

Authorities said the deputy contacted state police in an attempt to identify Mansur and a trooper responded to the scene.

The trooper recognized Mansur as a former civilian employee of the Department of Public Safety Radio Maintenance division. During questioning, authorities said Mansur admitted to identifying himself as state police and presenting a badge to the deputy.

Mansur had the badge confiscated and he was arrested. While being placed under arrest, authorities said that Mansur made several comments to the trooper alluding that he would regret arresting him and that he would slander him on social media.

Mansur was booked for false personation of a police officer and public intimidation.

Authorities were able confirm that Mansur did at one point work as a civilian employee for Radio Maintenance, but is no longer employed by DPS and has never been a commission trooper.
