Protesters clashed with riot police in the U.S. state of Missouri overnight after police reports released earlier on Friday said a black teen was a suspect in the theft of cigars from a store minutes before an officer shot him dead.

While Ferguson, Missouri, had been calmer over the last 24 hours after local law enforcement was replaced by state police led by an African-American captain, racially charged protests entered their sixth night since the Aug. 9 death of Michael Brown.

Highway Patrol Captain Ron Johnson said police fired a teargas canister at a crowd near a food and liquor store and broader violence and looting erupted.
