The FBI has sent nearly 100 additional agents to Ferguson, Missouri, to help law enforcement there as officials prepare for possible unrest ahead of a grand jury decision in the Michael Brown shooting.

A U.S. official said Friday that the agents will supplement the law enforcement presence. The official was not authorized to discuss the FBI plans by name and spoke on condition of anonymity.

A grand jury has been meeting to decide whether to indict Officer Darren Wilson in the Aug. 9 shooting of the unarmed black 18-year-old. It's not clear when that decision will be announced.

The Brown shooting has prompted weeks of unrest on the streets and occasionally violent clashes between police and protesters. Missouri Gov. Jay Nixon earlier this week activated the National Guard.
