FERGUSON, Mo. - Authorities have been working to prevent another night of violence in Ferguson and north St. Louis County.

Tear gas has been launched into the streets, according to police.

St. Louis County police spokesman Brian Schellman said that police tried to disperse crowds, and people in the crowds begun to throw items such as rocks and coins at police, which is what triggered the use of the tear gas.

Schellman also said that reports of a shooting near the apartments where Michael Brown was shot and a fire in another area have been unfounded.

Sunday night, two police officers were injured and 32 arrested during riots that broke out around West Florissant.

City of St. Louis Alderman Antonio French has been documenting the events of Monday in Ferguson, which has been compiled into a YouTube video.

Metro St. Louis tweeted that they have rerouted the No. 74 Florissant bus due to road closures and police activity.

Schellman said some arrests have been made, but he didn't know the amount.
