Federal authorities plan to unseal charges Monday against several people arrested in a series of weekend raids in Michigan, Ohio and Indiana, prosecutors in Detroit said Sunday.
At least seven people were arrested on charges that were under seal over the weeekend, a law enforcement source said Sunday.
The FBI would disclose no details of the raids, but the law enforcement source told CNN the arrests were unrelated to any terrorist plot. The source said the suspects were not planning attacks against government targets and the raids were unrelated to recent threats against members of Congress.
