PARMA -- Police say the incident occurred on Feb. 28 about 9:30 a.m. in the gymnasium at Parma Senior High School at 285 W. 54th Street.
The victim, a 14-year-old developmentally challenged student, was in gym class and was the apparent victim of a bullying incident that is under investigation.
During gym class, a 14-year-old boy repeatedly threw a volleyball at the victim from close range, striking him on the head. Enough force was used by the juvenile that the victim eventually fell to the floor.
A 13-year-old girl was seen laughing and encouraging the bullying and assault on the victim. The victim appeared disoriented. As he staggered back to his feet, the girl approached the victim and kicked him in the groin, causing him to fall to the floor again.
A substitute teacher walked over to the victim, who was still lying on the floor. The teacher dispersed a number of students who gathered to watch and then walked away from the victim.
The teacher walked over to another corner of the gym and continued instructing class while the victim was still face down on the floor. The teacher remained in the gym while another pair of boys approached the victim and began sliding into the victim as he was still lying on the floor.
A 14-year-old boy also dragged the victim face down by his feet across the gym floor. A 15-year-old boy and a 13-year-old boy squatted over the victim and simulated obscene acts near the victim's head while he lay motionless on the gym floor.
The teacher was cited for endangering children. Two boys and one girl were charged with assault. The other two boys were charged with disorderly conduct. The case is still under investigation and additional charges are possible after consultation with prosecutors.
The teacher, Gregg Mellinger, 49, of North Ridgeville, continued class with the victim on the floor. Authorities say the boy wasn't seriously injured.
