Police in the US city of Ferguson have made fresh arrests as part of its ongoing crackdown on protests over a grand jury decision in the case of the death of Michael Brown there.
At least 15 people were taken into custody on Friday during demonstrations demanding justice for unarmed black teenager Brown, who was shot and killed by white police officer Darren Wilson last summer.
The protests have been ongoing in dozens of US cities since the jury cleared Wilson on Monday.
Demonstrators also disrupted Black Friday shopping in many cities including in Ferguson where activists shut down malls.
In Chicago, New York, Seattle and northern California, protesters chained themselves to trains. Police arrested more than a dozen protesters in northern California on Friday.
On Monday, St. Louis County prosecutor Robert McCulloch said that Wilson would not be indicted and that he would not even face charges for killing 18-year-old Brown on August 9 in Ferguson.
Following the decision, violent protests against racial discrimination and police brutality in the United States broke out in dozens of cities and towns across the country.
Missouri Governor Jay Nixon has declared a state of emergency and deployed thousands of National Guard troops to the Ferguson area to quell violence.
