BATON ROUGE, La. — A Louisiana police officer shot and killed a man following a confrontation outside a Baton Rouge convenience store early Tuesday, authorities said, and protests at the scene grew after cellphone video surfaced apparently showing the shooting.

Two officers responded and had some type of altercation with the man in the parking lot, and one officer fatally shot the suspect, the statement said. Both officers have been placed on administrative leave, which is standard department policy, the statement added.

The store’s owner, Abdul Muflahi, told CBS Baton Rouge affiliate WAFB-TV the first officer used a Taser on Sterling and the second officer tackled him. Muflahi said that, as Sterling fought to get the officer off him, the first officer shot him “four to six times.”

The owner said Sterling didn’t have a gun in his hand at the time but he saw officers remove a gun from Sterling’s pocket after the shooting.
