A Baton Rouge Police officer who was seriously injured during a July 9 protest over the shooting of Alton Sterling has filed a lawsuit against the national Black Lives Matter movement and co-founder of the organization DeRay McKesson.  

"Protests in other cities staged by Defendants resulted in violence and property loss," states the lawsuit, which was filed Monday. "Defendants conspired to violate the law by planning to block a public highway. Defendants were in Baton Rouge for the purpose of demonstrating, protesting, and rioting to incite others to violence against police and other law enforcement officers."

"At the beginning the protest was peaceful until activist began pumping up the crowd," states the lawsuit. "DeRay McKesson was in charge of the protests and he was seen and heard giving orders throughout the day and night of the protests."  

The lawsuit claims the protesters began to "loot a Circle K" for water bottles that were later thrown at police officers.  

"When the Defendants ran out of the water bottles they were throwing at the Baton Rouge City Police, a member of Defendant Black Lives Matter, under the control and custody of the Defendants, then picked up a piece of concrete or similar rock like substance and hurled into the police that were making arrests."  

McKesson is part of a class action lawsuit that was filed in August on behalf of several individuals who were arrested the night of the protest. That case is assigned for a telephone conference with Magistrate Judge Erin Wilder-Doomes on Nov. 10, WAFB TV reports.
