FERGUSON, Mo. -- St. Louis County Police Chief Jon Belmar says a man who opened fire on officers in Ferguson, Missouri, is in "critical, unstable" condition after being struck when the officers returned fire.
The man has been identified by his father as 18-year-old Tyrone Harris, Jr. of St. Louis. He was a close friend of Michael Brown.
Belmar said at a news conference early Monday morning that plainclothes officers had been tracking Harris, who they believed was armed, during a protest marking the anniversary of the death of 18-year-old Michael Brown.
Belmar says Harris approached the officers, who were in an unmarked police van, and opened fire. The officers returned fire from inside the vehicle. They then pursued the man on foot.
The chief says Harris again fired on the officers. All four fired back.
Harris was taken to a hospital, where he underwent surgery.
He is in critical condition.
Belmar says the police shooting happened shortly after dozens of shots rang out around 11:15 p.m. Sunday, as protesters were gathered on West Florissant Avenue. The crowd went running for cover.
Brown, who was black and unarmed, was fatally shot by white Ferguson Police officer Darren Wilson. A grand jury and the U.S. Department of Justice declined to prosecute Wilson, but the shooting touched off a national "Black Lives Matter" movement.
