Ms Hargrave appeared to leave the meeting willingly after the officer approached her and asked her to do so, but in the hallway video showed that she was on the ground being handcuffed and asking "what are you doing?" repeatedly.
After the board approved the raise, Hargrave was again recognized by the board and voiced her frustrations.
She questioned the raise a time when pay teachers and other staff has stagnated, despite larger class sizes and improved outcomes for students.
"I am not, you just pushed me to the floor!"
"I have a serious issue with a superintendent or any person of leadership getting any type of raise", Hargrave said during the meeting.
According to KATC-TV, Hargrave addressed the school board during the public comments portion of the meeting focused on teacher salaries and pay raises.
The board was meeting to discuss a new three-year contract for Superintendent Jerome Puyau.
"His job is to make sure that we have orderly board meetings". While he did not witness everything that led to Hargrave's attest, he "absolutely" stood by the marshal, he said.
School board member Laurie Leblanc did speak out for Ms Hargrave after the incident, saying: "what happened here tonight, the way that females are treated in Vermillion Parrish.I have never seen a man removed from this room". She pulled back and said, "Don't put your hands on me".
LeBeouf added that Hargrave is "a great teacher, a great individual".
Hargrave was arrested for resisting an officer and remaining after being forbidden, but the school system is not pressing charges, KATC reported.
A Louisiana English teacher's criticism of the superintendent's $38,000 raise was met with handcuffs and a trip to jail.
A teacher's union lawyer is investigating, and while teachers were at work Tuesday, a School Board member says there is talk of a strike.
