The St. Louis suburb of Ferguson saw another night of tension on Tuesday but no violence ensued with police arresting more than 40 people.
The U.S. Attorney General is scheduled to arrive to the suburb on Wednesday to check on the federal investigation into the shooting death of Michael Brown, 18.
Tuesday night began peacefully, and police did not use any tear gas. But then officers put on helmets and shields as protesters lined up and began throwing water bottles at officers around midnight.
Unlike Monday, there were no molotov cocktails thrown or shootings overnight. Police did seize loaded handguns after death threats were made toward officers.
Brown was an unarmed black teenager who was fatally shot by police on August 9. A private autopsy confirms witness accounts that he was shot multiple times.
Prosecutors on Wednesday will begin presenting evidence to a grand jury investigating the case.
Brown will be laid to rest in a public funeral Monday. Reverend Al Sharpton is set to give the eulogy.
