Security Threat Unit (STU)

The Security Threat Unit (STU) is the central repository for all security risk group information received from Norfolk Sheriff’s Office staff, outside law enforcement agencies, and any other sources deemed credible.

STU is responsible for identifying and tracking any gang related activity in the jail and investigates most criminal offenses that may occur inside the jail (drugs, weapons, serious assaults). STU also consists of two Narcotics Detection Dog Teams.
