A Black Lives Matter protest took place outside a Stop and Shop in Brooklyn Saturday following the death of a Flatbush man.

Organizers say that they are calling for a boycott of the grocery chain after Ralph Nimmons, 51, died following an incident at the store on Flatbush Avenue in Brooklyn earlier this month.

Witnesses say that there was an altercation back on April 14 between Nimmons and store employees because they believed he was trying to steal food.

Nimmons had a heart condition and was pronounced dead at the hospital.

"We have cooperated fully with the police and are continuing to do everything we can to aid their investigation,” a Stop and Shop spokesperson said in a statement to News 12.  

Nimmons’ family and their attorney want to see the chain release surveillance video from the incident. They say they were told by witnesses that store employees knocked Nimmons down, dragged him on the floor and that at least one person was on top of him.

The case is currently under investigation by the Brooklyn District Attorney's Office.
