Police are categorizing the shooting as a “targeted attack", reports CNN.

“This was not just a random act of someone showing up and randomly shooting citizens of Baton Rouge,” Lt. Bryan Ballard, commander of BRPD’s Homicide Division, during a press conference Sunday, told CNN.

A law enforcement source tells CNN around 1:30 a.m. local time, witnesses at Dior Bar & Lounge said a fight broke out between two groups of customers, and multiple people pulled out guns and started shooting.

An investigation into the incident is ongoing.
