Six men transferred into the Bulloch County Correctional Institute last week face additional charges after refusing to submit to a drug test. There was no fight, but a "general disturbance" was caused when one man refused to submit to the test and would not sign papers, then five others followed suit, said BCCI Warden Chris Hill. German Cameron, 35, of the Bulloch County Correctional Institute, was charged with obstruction, while five others were charged with felony obstruction and riot in a penal institution, according to Bulloch County Jail records.
