Tennessee Bureau of Investigation agents charged four suspects, including a Lebanon man, with assault of a male patient at the Middle Tennessee Mental Health Institute on Stewarts Ferry Pike in Nashville.
In May, state mental health Commissioner Doug Varney requested TBI agents conduct an investigation into an incident where a patient was assaulted.
The investigation revealed four former employees, who were psychiatric technicians at the time, kicked the patient in the face and struck the patient multiple times in the chest, agents said. The patient was housed at the facility for a court-ordered competency evaluation.
Jonathan Hambrick, 33, of Lebanon, Edward Fisher, 49, of Gallatin, Mark Williams, 52, of Nashville and Charles Woods, 48, of Old Hickory, were the former employees named as suspects in the case.
On March 21, a Davidson County grand jury returned indictments on the four former employees. Each was charged with assault and official oppression.
TBI special agents arrested the suspects Monday afternoon with assistance from Metropolitan Nashville and Gallatin officers. All four suspects were booked in at the Davidson County Jail and each held on $10,000 bond.
