Emergency vehicles could be seen outside a Walmart in Baton Rouge, after reports of gunfire in the store on Tuesday.

Authorities believe the incident was the result of an altercation that escalated between two customers, reports say. According to police cited in reports, one bystander was injured during the shooting.

One suspect has reportedly been apprehended, while another remains at large.

It follows a mass shooting in a Walmart, which killed 22 and injured 24 others in El Paso just days before.
