It all happened last Friday at Creekside Elementary School.
The girl was crying in the principal's office when police arrived.
The report says the girl knocked over a shelf that hurt the principal, then bit a door knob and jumped on the paper shredder.
It also says Salecia tried to break a glass frame above the shredder.
Officers tried to calm the child down, but she resisted.
That's when she was handcuffed, the police report states.
Salecia was taken to the police station and charged with simple assault and battery.
She will not have to go to court because of her age.
"Our policy is that any detainee transported to our station in a patrol vehicle is to be handcuffed in the back," Milledgeville Chief of Police Dray Swicord told WMZA.
"There is no age discrimination on that rule," Swicord added.
But Salecia's father told WMZA that he's upset that his young daughter was put in handcuffs.
"A 6-year-old in kindergarten. They don't have no business calling the police and handcuffing my child," Earnest Johnson said.
"Call the police? Is that the first step? Or is there any other kind of intervention that can be taken to help that child?" asked Salecia's aunt, Candace Ruff
"She might have misbehaved, but I don't think she misbehaved to the point where she should have been handcuffed and taken downtown to the police department," Ruff told WMZA.
Salecia's mother, Constance Ruff, said her daughter was suspended from school until August.
"She has mood swings some days, which all of us had mood swings some days, Ruff explained.
"I guess that was just one of her bad days that day."
