Two men suspected of buying explosives they planned to detonate during protests in Ferguson, Missouri, once a grand jury decides the Michael Brown case, were arrested on Friday and charged with federal firearms offenses, a law enforcement official told Reuters.
Word of the arrests, reported by a number of media outlets Friday, came ahead of the grand jury's widely anticipated decision on whether the white police officer who fatally shot Brown, an unarmed black teenager, should be indicted on criminal charges.
The Aug. 9 slaying of 18-year-old Brown under disputed circumstances became a flashpoint for U.S. racial tensions, triggering weeks of sometimes violent protests in the St. Louis suburb by demonstrators calling for officer Darren Wilson's arrest.
He was instead placed on administrative leave, and Ferguson has been bracing for a new wave of protests, especially if the grand jury chooses not to indict Wilson. An announcement was believed to be imminent.
Against this backdrop of heightened tensions, according to a law enforcement source, two men described as reputed members of a militant group called the New Black Panther Party, were arrested in the St. Louis area in an FBI sting operation.
As initially reported by CBS News, the men were suspected of acquiring explosives for pipe bombs that they planned to set off during protests in Ferguson, according to the official, who spoke to Reuters on condition of anonymity because he was not authorized to publicly discuss the case.
The official said the two men are the same pair named in a newly unsealed federal indictment returned on Nov. 19 charging Brandon Orlando Baldwin and Olajuwon Davis with purchasing two pistols from a firearms dealer under false pretenses.
Both men were arraigned on Friday in federal court, the law enforcement source said.
