Unrest continues in St. Louis after police shoot unarmed teen

ST. LOUIS, Missouri (NEWSCHANNEL 3) - It was a second night of unrest in suburban St. Louis, where police shot and killed an unarmed black teenager over the weekend.

Police had to use tear gas Monday night to break up an unruly crowd protesting the death of 18-year-old Michael Brown.

At least five people were arrested.

The unrest came, despite calls for calm from Brown's parents.

Brown was shot to death on Saturday during an altercation with police.

At least two witnesses said a police officer shot the unarmed teen as he had his arms raised.

On Monday, community leaders pledged to keep the pressure on police and find out exactly what happened.

"No matter what, we're going to stay committed until this is solved, so this never happens again to anybody's child," said Chuck Alphin Jr, of Building Life Foundations.

A crowd of residents protested in front of the Ferguson Police Department all night to show their support for Brown.

Dozens of officers patrolled the streets until the early morning.

The FBI and the U.S. Department of Justice have opened tandem investigations into this case.
