Several members of a Michigan militia have pled not guilty to charges surrounding their alleged plot to kill police officers and make other attacks.

Eight of nine suspects from the Hutaree group were arraigned Wednesday in U.S. District Court in Detroit. The ninth suspect appeared in court in Indiana and will be arraigned in Michigan later.

U.S. Magistrate Judge Donald Scheer denied their request to be released on bond.

The militia's ringleader, David Brian Stone, and his son are among those being charged.

The eight men and one woman were arrested during a series of raids by the FBI in Michigan, Indiana and Ohio.

The group's Web site says their purpose was to prepare "for the end time battles to keep the testimony of Jesus Christ alive."
