A 19-year-old man remained in custody Wednesday, three days after authorities say he was arrested on suspicion of beating his 5-month-old son.
Chris Wayne Freeman of Cumming has been charged with aggravated battery and cruelty to children, according to the Forsyth County Sheriff's Office.
Freeman is being held at the Forsyth County Detention Center, where a jail spokeswoman said his bond has been set at $54,692.
Sheriff's Investigator Matt Allen said the aggravated battery charge "says a lot about the seriousness" of the child's injuries.
The sheriff's office and the Georgia Division of Family and Children's Services are investigating.
Sheriff's Lt. Col. Gene Moss said authorities think the injuries were the result of "an intentional act by the father."
Moss said a criminal investigation began when Northside Hospital-Forsyth alerted authorities to a baby boy who was being treated for unexplained head injuries.
The infant, who authorities say is expected to survive, has since been moved to Children's Healthcare of Atlanta at Scottish Rite. The extent of his injuries is still being determined.
Sheriff's Capt. Paul Taylor said they are looking into the child's past to "determine not just what happened on that day, but what may have happened previously with this child."
Citing the sensitivity of the case, authorities declined to release information about the child's mother. They did say, however, that the injuries occurred at a home in Cumming
