Man who opened fire on officers in Ferguson critically injured: County police chief [Photos] [Video]

1FERGUSON, Mo.
2-- A man who authorities say opened fire on officers in Ferguson, Missouri, on the anniversary of Michael Brown's death was critically wounded when the officers shot back, St. Louis County's police chief said early Monday.
3Chief Jon Belmar said at a news conference that officers had been tracking the man, who they believed was armed, during a protest marking the death of Brown, the black, unarmed 18-year-old whose killing by a white Ferguson police officer touched off a national "Black Lives Matter" movement.
4The man approached the officers, who were in an unmarked police van, and opened fire, Belmar said.
5The officers returned fire from inside the vehicle and then pursued the man on foot when he ran.
6The man again fired on the officers, the chief said, and all four officers fired back.
7He was struck and fell.
8The man was taken to a hospital, where Belmar said he was in "critical, unstable" condition.
9The elder Harris told the newspaper shortly after 3 a.m. that his son had just gotten out of surgery.
10None of the officers was seriously injured.
11All four have been put on standard administrative leave.
12They were not wearing body cameras, Belmar said.
13The shooting happened shortly after a separate incident that the chief called "an exchange of gunfire between two groups" rang out around 11:15 p.m. Sunday while protesters were gathered on West Florissant Avenue, a business zone that saw rioting and looting last year after Brown's killing.
14The shots sent protesters and reporters running for cover.
15The chief said an estimated six shooters unleashed a "remarkable" amount of gunfire over about 45 seconds.
16Belmar waved off any notion that the people with the weapons were part of the protest.
17"They were criminals. They weren't protesters," he said.
18The man who fired on officers had a semi-automatic 9 mm gun that was stolen last year from Cape Girardeau, Missouri, according to the chief.
19"There is a small group of people out there that are intent on making sure that peace doesn't prevail," he said.
20"There are a lot of emotions. I get it. But we can't sustain this as we move forward."
21Early Monday, another reported shooting drew officers to an apartment building in the area.
22Two men told police they were targeted in a drive-by shooting near the memorial to Brown outside Canfield Apartments.
23A 17-year-old was shot in the chest and shoulder while a 19-year-old was shot in the chest, but their injuries were not life-threatening, the St. Louis County Police said in a news release.
24Separately, police said a 17-year-old male has been charged with unlawful use of a weapon and one count of resisting arrest after he fired shots near the protesters late Sunday.
25He is being held on $100,000 bond.
26The anniversary of Brown's killing, which cast greater scrutiny on how police interact with black communities, has sparked days of renewed protests, though until Sunday they had been peaceful and without any arrests.
27Before the gunfire, protesters were blocking traffic and confronting police.
28One person threw a glass bottle at officers but missed.
29For the first time in three consecutive nights of demonstrations, some officers were dressed in riot gear, including bullet-proof vests and helmets with shields.
30Police at one point early Monday shot smoke to disperse the crowd that lingered on West Florissant, Belmar said.
31One officer was treated for cuts after a rock was thrown at his face, and two officers were pepper-sprayed by protesters, county police spokesman Officer Shawn McGuire said in an email.
32Five people were arrested, according to records McGuire released.
33Several other peaceful events earlier Sunday were held to mark the anniversary.
34Brown's father, Michael Brown Sr., led a march through town.
35It started at the site where Brown was fatally shot by officer Darren Wilson.
36A grand jury and the U.S. Department of Justice declined to prosecute Wilson, who resigned in November.
37Later, a few hundred people turned out at Greater St. Mark Family Church for a service to remember Brown, with his father joining other relatives sitting behind the pulpit.
38Organizers of some of the weekend activities pledged a day of civil disobedience on Monday, but have not offered specific details.
