More than 200 teens were in the Mall of Louisiana's food court when a large fight broke out just before 6 p.m. Saturday, although it wasn't clear how many were actually fighting.
No injuries were reported. The Advocate quotes the East Baton Rouge Parish Sheriff's office as saying it plans to charge a number of people.
Witnesses told the newspaper that the trouble started after Instagram users posted an invitation to their followers on social media telling them to come and meet them in person at the mall.
Police corralled unaccompanied youths until parents arrived to pick them up.
