An explosive device deployed by police flies in the air as police and protesters clash Wednesday, Aug. 13, 2014, in Ferguson, Mo. Protests in the St. Louis suburb rocked by racial unrest since a white police officer shot an unarmed black teenager to death turned violent Wednesday night, with people lobbing molotov cocktails at police who responded with smoke bombs and tear gas to disperse the crowd.

Thousands of protesters took to the streets in Ferguson on Sunday night. The situation quickly spiraled out of control when police fired tear gas into the crowd well before the midnight curfew. It’s unclear what prompted the police action.

Capturing the dramatic events for the world was Mustafa Hussein, a student who works at a local all-volunteer music station, Argus Radio. The station is using video equipment it purchased to live-stream concerts to broadcast the protests in Ferguson.

Tonight, as tens of thousands of people around the world watched, Hussein was threatened by an officer wielding a weapon. “Get the fuck out of here! You get that light off or you’re getting shot with this!,” the man shouts. That portion of the live-stream was uploaded to YouTube:

Undeterred, Hussein continued broadcasting. Subsequently, he can be heard reporting the incident to a different officer and other reporters. He then called his dad to tell him he loved him.
