St. Louis County Police released a video on Tuesday that they said shows a suspect, who has been accused of firing on police, drawing a pistol from his pants during protests in strife-torn Ferguson, Mo.
Tyrone Harris, 18, was shot by police and is in critical condition. He has been charged with four counts of assault on law enforcement, five counts of armed criminal action, and one count of shooting at a vehicle. Bond for Mr. Harris, who is black, was set at $250,000.
The incident occurred on Sunday in the St. Louis suburb where largely peaceful demonstrations over police shootings of unarmed black men have been punctuated by violence.
The 13-second video taken from a surveillance camera at an insurance agency shows a group of people milling about during Sunday night's protests marking the one-year anniversary of the fatal shooting of an unarmed black teenager by a white police officer.
During the video shots are fired and a young man can be seen brandishing what looks like a pistol.
St. Louis County Police said, "The video shows Harris grab a handgun out of his waistband once shots are fired during the protest in the West Florissant corridor."
Harris's father said his son did not have a gun.
"He was running for his ... life because someone was shooting at him," Tyrone Harris, Sr. said in a telephone interview from his St. Louis-area home before the video was released.
According to St. Louis city court records, the younger Harris was free on bail awaiting trial on charges of stealing a motor vehicle, theft of a firearm and resisting arrest.
Lighter police presence
A state of emergency that was declared on Monday for the Ferguson area was still in effect on Tuesday. Protesters have been marching and staging acts of civil disobedience to mark the anniversary of the death of 18-year-old Michael Brown.
Brown's death was one in a series of police killings of unarmed black men in US cities including New York, Baltimore, North Charleston, South Carolina and Cincinnati that renewed the debate on race and justice and led to the "Black Lives Matter" movement.
By Tuesday afternoon there had been no major rallies in the St. Louis area, and there was a lighter police presence on the streets of Ferguson. Work crews were cleaning and repairing a parking lot where a some demonstrators had scooped up gravel to throw at police.
Brian Fletcher, a former mayor of Ferguson now on the city council, said he believed that violence the city has seen over the past year was coming to an end.
"If this is the worst that's going to happen, then we'll survive," said Fletcher, standing in the "I Love Ferguson" store he opened in October to raise money for city businesses and institutions that were damaged in riots last year.
Sunday night's violence included a drive-by shooting and several instances of rocks and bottles being hurled at police.
Rallies over the past few days have been mostly peaceful, but late on Monday police carrying shields rushed a crowd of protesters prompting many to scream and run. Protesters who were arrested were suspected of throwing frozen water bottles and rocks at police and other offenses, according to the St. Louis County Police Department.
Adding to the tension, four white men carrying military-style rifles and sidearms, who said they are part of a group called "Oath Keepers," patrolled Ferguson's streets.
The group describes itself as an association of current and former US soldiers and police who aim to protect the US Constitution. The Southern Poverty Law Center, a non-profit civil rights organization, has described the "Oath Keepers" as a "fiercely anti-government, militaristic group."
The St. Louis County police chief condemned their appearance in Ferguson.
