Police in Louisiana say a man was jailed after posting a social media video in which he says he wants to shoot and kill a police officer.

Sgt. Brian Griffith of the Bossier (BOH'-zhur) City Police Department says the man made the video while sitting in a car that was behind a police unit at a fast-food drive-thru in the northwest Louisiana city early Friday.

The suspect, 19-year-old Kemonte (kee-MAWN'-tee) Gilmore, turned himself in Friday afternoon. He faces a charge of public intimidation. He was jailed on $500,000 bond. It was not immediately clear if he has a lawyer who could speak on his behalf.

Griffith wouldn't disclose where the video was posted. He said the video showed Gilmore in possession of a handgun that has not been recovered.
