The Patterson Mill school resource officer rushed to Technology Alley at the school to find the victim on his hands and knees with blood on his face, arm and hand, according to the police report.
The young man's face and forehead were swollen and he was taken to Upper Chesapeake Medical Center for treatment, according to the report.
The sheriff's deputy reviewed camera footage and saw nearly out of camera range another student come toward the boy, lift him up and slam him to the floor, according to the report. The deputy identified the student believed responsible, but that student had already left with a parent.
The 17-year-old Abingdon boy, who sources say is the rape victim's brother, is being charged as a minor with first- and second-degree assault and disturbing school operations.
The month and year of the assault victim's birth match that of Reddish and sources confirmed that Reddish was the victim.
Cassilly said there are some issues with the charges against the 17-year-old.
"Normally a person who is 17, 16 or 17 who is charged with first-degree assault is charged as an adult," Cassilly said.
He went on to explain that the circumstances of the incident fit better with a charge of second-degree assault.
"Although it was charged as first-degree assault the recommended charges are second-degree assault," Cassilly said.
He said it is likely that the 17-year-old will not be charged as an adult.
