A man was fatally shot by a police officer Friday after a struggle outside of a California convenience store that was captured on a bystander's video.

The Huntington Beach police officer was speaking with the man outside of a 7-Eleven around 9:30 a.m. when a confrontation broke out and the officer opened fire, Officer Angela Bennett, a police spokeswoman said.

Police released no other details, but two short video clips posted on social media sites for the OC Hawk news service appeared to show the encounter.

One clip shows an officer struggling to subdue a man in a parking lot. While on the ground, the man grabs something from the officer's belt and the officer pulls out his gun and backs away.

In a second clip, the man jumps to his feet and almost immediately is shot. Eight rounds can be heard as the man stumbles backward and then collapses against a wall.

The officer can then be heard speaking into his radio, saying, "the suspect is down."

Bennett said the department is aware of video that captured the shooting and would review all evidence in the case. "We're still in the very early stages of this investigation," she said Friday afternoon.

The shooting occurred in the vicinity of Marina High School, which was put on lockdown as a precaution.
