A second East Texas man is in custody, suspected of being part of a white supremacist group that's accused of robbing a neighbor and beating him with a baseball bat.
One man has already been charged in Monday's alleged beating. But this second man isn't charged for that same crime.
Samuel Scott Castleberry of Smith County was arrested for an alleged road rage incident Wednesday night. The alleged victim says Castleberry rammed his SUV into the back of her car and pointed a gun at her and her child.
Castleberry is charged with aggravated assault with a deadly weapon and child endangerment.
Authorities say they later found an explosive device in his storage shed. The ATF bureau will determine whether to charge him for possessing that device.
