Jamie Lynn Spears wields a knife and breaks up a fight at a Louisiana Pita Pit in new surveillance video from an incident that reportedly occurred in December.

Jamie Lynn Spears Wields Knife [VIDEO]

In the newly released video, Spears, little sister of pop star Britney Spears, can be seen standing back as a group of men get into a fist fight. People are knocked down in the scuffle, and Spears’ friend was allegedly hit. Spears is then seen marching behind the counter, grabbing a large kitchen knife and waving it around to get the men’s attention and encourage them to stop.

Based on the video, it’s clear Spears had a plan and knew what she was doing. At one point, she stops and appears to tell a Pita Pit employee of her plans to break up the fight.

The story or the brawl originally broke on Dec. 30, after the early morning Dec. 28 incident, but the surveillance video didn’t leak until Tuesday, Jan. 13. Pita Pit called the police, but Jamie’s friend who had been knocked down during the fight said she didn’t want to press charges and no one was arrested. “A group of males got into an altercation and for some reason Jamie Lynn Spears ran behind the counter and picked up a bread knife. Our management called the police immediately and thankfully nothing else happened,” said the Pita Pit owner Jack Brighenti.

Spears posted a photo to Instagram earlier that night, on Dec. 27, of her and a friend. It appears she was celebrating her friend’s birthday before the altercation occurred.

Happy Birthday @brandiblair22 !!! #nofilter
