A police officer in University City, Missouri was wounded in a shooting late Monday, but at this point it's not clear whether the shooting is related to protests in nearby Ferguson, authorities said.
The officer's condition is unknown.
The St. Louis County Police Department confirmed the shooting, saying a search for the suspect is underway.
Local and national protests followed Monday's announcement that a grand jury decided not to indict Ferguson police officer Darren Wilson for the Aug. 9 shooting of unarmed teenager Michael Brown.
