Black Lives Matter: Louisiana Police shoots black man 11 times outside store, protests erupt | WATCH

The fatal shooting of a 31-year-old Black man by police in Lafayette, Louisiana, on Friday night has sparked a state probe.

The Louisiana State Police Bureau of Investigations announced in a press release Saturday that it is investigating the killing of Trayford Pellerin on Friday night.

The incident in Lafayette, a city about 56 miles west of Baton Rouge, occurred after police responded to a report of a disturbance at around 8 p.m. "involving a person armed with a knife at a convenience store," the state police investigative bureau said in the release.

Upon arrival, officers encountered Pellerin in the parking lot of the convenience store.

As officers "attempted to apprehend Pellerin, he fled the scene and a foot pursuit ensued," the release said. "Officers deployed Tasers as they pursued Pellerin, but they were ineffective."

Pellerin tried to enter inside another convenience store at a gas station while "still armed with a knife," the release said. "Officers discharged their weapons and he was struck by gunfire."

Pellerin was taken to a hospital where he was pronounced dead.

Part of the police pursuit and the shooting was caught on video by a woman who witnessed the incident while inside a car near the gas station.

The video, which was posted on social media, shows a Black man wearing a white T-shirt with long pants being pursued by police.

The shooting Friday night was captured on video, and the state ACLU condemned what it described as a “horrific and deadly incident of police violence against a Black person.” Both the ACLU and the Southern Poverty Law Center quickly called for an investigation.

Pellerin's death prompted a crowd of protesters to gather Saturday and demonstrate against the latest fatal police shooting. Officers in riot gear fired smoke canisters on Saturday night to get the crowd to disperse, Trooper Derek Senegal said. No tear gas was deployed, he said.
