“Federal agents arrested a Mississippi martial arts instructor early Saturday morning after his home and a former business were searched as part of an investigation into ricin-laced letters sent to President Barack Obama and two other public officials,” Reuters reports.
Prosecutors dropped charges against another Mississippi man earlier this week after a search of his home revealed no incriminating evidence.
