Shoppers at a Walmart in Baton Rouge caused a panic when they fled the store on Tuesday amid fears that a shooting took place — but it was unclear if a shot had actually been fired.

The false alarm — which took place just days after a massacre at the store’s location in El Paso — was sparked when two men got into a fight and drew their firearms inside the Louisiana megastore.

“Panicked customers were running from the front and rear entrances to the store, and told initial responding deputies that they could hear ‘popping’ sounds that they believed to be gun shots,” East Baton Rouge Sheriff Sid Gautreaux said.

He added that “upon reviewing the (store surveillance) video, investigators determined initial information obtained from eyewitnesses, and the 911 calls, was not accurate.”

Gautreaux said the video confirmed that the two men did get into an argument and that “guns were drawn.”

Police nabbed one of two men allegedly involved in the argument and he did have a gun. Forensics tests will determine if was fired at all.

Gautreaux defended the over-the-top response by police.

“Given the recent events in El Paso and Dayton, and given the initial information we received via 911 calls and witnesses exiting the store, we responded with what we feel is appropriate,” he said.

“The national climate regarding these incidents has the nation on edge.”
