St. Louis County police released surveillance footage of the moments leading up to the Sunday, Aug. 9 shooting in Ferguson, Missouri that injured 18-year-old Tyrone Harris. The shooting occurred feet away from protesters who were marking the one-year anniversary of the shooting death of Michael Brown.

Harris can reportedly be seen at the end of the video, in a white T-shirt, pulling out a gun and pointing it as he runs out of frame.

According to police:

The St. Louis County Police Department is releasing surveillance video pertinent to the investigation of the officer involved shooting of Tyrone Harris that occurred on August 9, 2015. The surveillance video is from Solo Insurance Services, located at 9197 W. Florissant, St. Louis, MO 63136. Detectives from the Crimes Against Persons Unit have identified the person in the video as Tyrone Harris. The video shows Harris grab a handgun out of his waistband once shots are fired during the protest in the W. Florissant corridor.

Harris was injured when gunfire broke out between what police say was two rival groups. As Harris fled the scene of the shooting, officers say he fired on an unmarked police car and the officers returned fire, striking Harris.

Harris remains in critical condition and was charged on 10 counts for the shooting.

The incident was responsible for a "state of emergency" that was implemented in St. Louis County on Monday, ahead of Monday night's demonstrations.

Other video surfaced Monday that appears to show the shooting from another angle.
