Four adults and a minor were injured in a Sunday afternoon shooting that critically injured two of them at a north Baton Rouge market and convenience store, according to police.  

Baton Rouge Police officers responded around 3:15 p.m. to Carlin's Food Mart in the 2900 block of Plank Road following reports of gunfire, officials said.

Medical responders brought four people to the hospital, and another arrived in a private vehicle, EMS spokesman Brad Harris said. 

Two were listed in critical condition while the others were stable, said Baton Rouge Police spokesman L'Jean McKneely. He added that a minor, whose age and condition wasn't immediately available, was among those wounded in the shooting.  

The shooting happened outside the store, and detectives were investigating whether any shots were fired inside, McKneely said. 

Investigators taped off the store's parking lot of the store and several officers were milling around in and outside the building, which sits on a busy road. 

Officials aren't sure what prompted the shooting and no arrests were immediately made, McKneely said.

In 2015, a 19-year-old was fatally shot in the store's parking lot in what appeared to be a robbery, authorities said at the time.

Federal agents arrested Sidney Paul Ellois III, who was 18 at the time of the February shooting. He was later sentenced to 15 years in prison for manslaughter.
