(NEW YORK) -- Federal authorities in Ferguson, Missouri, charged two men with lying on forms to purchase guns ahead of the grand jury decision in the police shooting of Michael Brown.
Olajuwon Davis and Brandon Baldwin only faced those charges as of late Friday, but sources told ABC News that authorities were looking into whether they tried to acquire ready-made explosives and other weapons ahead of the decision, which is expected soon.
Neither man had a lawyer listed on court documents.
The Drug Enforcement Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives played a part in the arrest.
The two men are believed to be associated with radical groups and the charges that were filed were intended to "take them out of the rotation," said one source.
The FBI has sent about 100 agents to the St. Louis area to help deal with any problems that could arise from the grand jury decision.
St. Louis authorities said earlier Friday that the grand jury was still meeting. The panel will decide whether to indict Ferguson Police Officer Darren Wilson for shooting Brown, who was unarmed, on Aug. 9.
The FBI declined to comment on its operation in Ferguson.
Missouri Gov. Jay Nixon declared a state of emergency earlier this week and activated the Missouri National Guard to help keep order if necessary.
Michael Brown Sr., the father of the slain teen, issued a videotaped appeal this week for protester to remain peaceful whatever the verdict.
