Louisiana's attorney general has sued a local school board over a meeting disrupted by the video-recorded arrest of a teacher who was roughly handcuffed on a hallway floor after she criticized the district superintendent's pay raise.

Attorney General Jeff Landry's lawsuit filed Thursday accuses the Vermilion Parish School Board and its members of violating the state's Open Meetings Law.

The suit asks the court to nullify all board actions at the Jan. 8 meeting, including its vote to raise Schools Superintendent Jerome Puyau's salary by roughly $30,000. The suit also seeks civil penalties against board members.

A deputy city marshal arrested middle school English teacher Deyshia Hargrave after escorting her out of the meeting room and handcuffing her in the hallway. A viral video of the arrest sparked widespread outrage.
