Protesters remained on the road in Ferguson, Missouri overnight, even as police fired tear gas and flash grenades in their direction.
Officers in riot gear formed a line several officers deep, then moved in on demonstrators, arresting several who broke an order to keep moving.
Missouri State Highway Patrol Captain, Ron Johnson, says those disrupting the community are from out of town. "I am not going to let the criminals that have come out here from across this country or live in this community define this neighborhood or define what we're going to do to make it right."
Members of the clergy have been trying to restore order. "We just want people to obey the law of the land."
National Guard units are now in the city protecting a police staging area but could be called on if things get worse.
Tensions in the predominately black community have been heightened since Michael Brown, an unarmed black teenager, was shot to death by a white police officer, Darren Wilson, last week.
An independent autopsy done by the Brown family revealed he was shot six times, including twice in the head.
Witnesses have said Brown had his arms up and was surrendering at the time.
But a Forensic expert who worked on the autopsy said Monday that is still inconclusive.
A grand jury may begin hearing testimony from witnesses tomorrow to decide whether to return an indictment in the case.
Attorney General Eric Holder is heading to Ferguson Wednesday as the Justice Department performs a third autopsy on Brown's body. The Ferguson-Florissant School District has canceled classes for the rest of the week because of the instability.
