International desk, September 17: New protests have broken out in the US city of St Louis, where a white former policeman was found not guilty of murdering a black suspect in 2011.
More than 33 protesters were arrested and 11 police officers were injured in Friday night’s scuffles.
The defendant, Jason Stockley, 36, was cleared of murdering Anthony Lamar Smith, 24, after a car chase.
Mr Stockley, a serving police officer at the time, was recorded during the pursuit saying: “Gonna kill this [expletive], don’t you know it.”
On Saturday evening, police were out in force as demonstrators rallied in St Louis.
Crowds marched through a shopping centre in the Des Peres suburb, blocking one major road.
So far there have been no reports of violence.
The home of St Louis Mayor Lyda Krewson suffered considerable damage, police say, as protesters ignored orders to disperse.
By late evening police declared the gathering an “unlawful assembly”.
As a result of the protests, a concert by the Irish rock band U2 due to take place in St Louis on Saturday night was cancelled.
The concert’s organisers say they took the decision after police informed them that they were “not in a position to provide the standard protection for our audience”.
Mr Smith was a new father and engaged to be married when he was killed on 20 December 2011.
Mr Stockley and his partner said they believed they had observed Mr Smith engaging in a drug deal outside a restaurant.
Police dashcam video and surveillance footage showed Mr Smith reversing his car into the police vehicle twice during his attempt to drive off.
After a three-minute high-speed chase, Mr Stockley told his partner, who was in the driver’s seat, to ram Mr Smith’s car.
Mr Stockley then ran to Mr Smith’s window and fired five shots, hitting him each time.
