Cobb Sheriff’s deputy arrested after allegedly bringing contraband into jail

A former Cobb County Sheriff Deputy now finds himself behind bars after contraband was discovered in the county jail last week. Following a week-long investigation, Dyimond Johnson was arrested and charged with transporting contraband into the county jail.

A spokesperson said a “controlled substance” was discovered last Monday and the office opened criminal and internal investigations. 

Johnson, 30, was fired immediately and faces four felony charges related to the incident, including violating his oath of office and delivering contraband across the jail’s guard line. Johnson was hired in September 2021 and underwent a rigorous background check prior to joining the Sheriff’s office. He is now being held without bond in jail.

A warrant for the incident was not immediately available, and the sheriff’s office said it could not provide further information while the investigation was ongoing.
