A Ferguson, Mo., police officer was shot Saturday night, St. Louis County law enforcement officials confirmed to CBS affiliate KMOV.

Officials say the officer was shot in the arm while on routine patrol and interrupted a burglary in progress at a business. KMOV reports the officer is expected to be okay. But police say the suspect, a slender African-American man with dreadlocks, fled on foot and is still at large. Police have closed roads in the area as they search for the suspect.

The officer's condition was not released, but he was removed from the scene and taken to an area hospital.

Police set up a staging area near West Florissant and Stein, close to the area where protests took place last month after the shooting death of Mike Brown, an unarmed 18-year-old by Ferguson policeman Darren Wilson.

Some unrest had erupted Friday after Ferguson Police Chief Tom Jackson released a videotaped apology to Brown's parents for the shooting.

The city has been the scene of major unrest since the Aug. 9 shooting of Brown. Dozens were arrested after days of demonstrations and clashes between protesters and police.
