Missouri authorities are drawing up contingency plans and seeking intelligence from U.S. police departments on out-of-state agitators, fearing that fresh riots could erupt if a grand jury does not indict a white officer for killing a black teen.

An Ohio grand jury on Wednesday decided not to press charges against two police officers who fatally shot a man while he held a pellet gun at a Dayton-area Walmart in August, prosecutors said.

After weeks of heavy criticism and calls for his ouster, the police chief of Ferguson, Missouri, issued a video apology on Thursday to the parents of Michael Brown, the black teenager shot to death by a white police officer last month.
