Milwaukee riots: Violent protests break out after police officer shoots man dead
At least two efforts to push protesters back from the main intersection in the north of the city where the majority of the unrest occurred.
The violence came after an unnamed 23-year-old man was shot dead while trying to flee from police at a traffic stop.
Police said the man – who had a criminal record – had a stolen handgun but it was not clear whether he was brandishing it when he was shot.
Neither his race nor that of the officer who fired the fatal shot have been identified.
Mr Barrett told a news conference that the shooting was being investigated and the officer was wearing a body camera.
The unnamed 24-year-old officer has been put on administrative duty. He has been at the Milwaukee police department for six years.
