(CNN) -- A Ferguson, Missouri, police officer was shot Saturday evening, according to St. Louis County Police spokesman Brian Schellman.

The officer is alive.

Demonstrators have taken to the streets of Ferguson since unarmed African-American teen Michael Brown was shot by a white Ferguson police officer in early August.

Tensions reignited in the Missouri town on Thursday night after a late-night appearance by Police Chief Thomas Jackson to address the crowd. A scuffle ensued, and arrests were made.
