LOUISVILLE, Ky. (WDRB) -- Three Jeffersontown High School students have been arrested and charged with assault, following a Feb. 29 incident that left a classmate hospitalized with serious injuries.

Henry Perkins, 18, was arrested Thursday and charged with second-degree assault, while two other juvenile students -- one male, one female -- were arrested and charged with second-degree assault earlier this week.

Perkins is being held in Louisville Metro Corrections on a $10,000 bond and will be arraigned Friday.

Jeffersontown Police Chief Rick Sanders said the incident happened around 2 p.m. Feb. 29 in the woods behind the school during school hours. The school is located at 9600 Old Six Mile Lane.

"A group of students skipped school and were drinking heavily and an argument led to physical violence," Sanders said. "They punched, kicked and stepped on him while lying on the ground. He was struck and kicked in face, torso and groin area."

Sanders said the juvenile victim "received serious injuries and was hospitalized for several days."

"He sustained a closed head injury, swelling of the brain and numerous contusions to his face and torso," Sanders said. "He was unconscious when they found him and he was placed on a ventilator until 11 p.m. that night."

Sanders said the incident remains under investigation and more arrests are possible.

Lenora Moore, the mother of one of the juvenile suspects, said her son was only trying to break up the fight and should not be held at a juvenile detention center. 

"After the fourth or fifth punch to the gut and the second or third pop to the top of the head, my son got up and moved the little boy back," Moore told WDRB News. 

She said she's only been able to have a five minute phone conversation since Wednesday when he was taken into custody. She feels police and school officials are keeping her in the dark when she said she knows her son is innocent because of the nature of his character. 

"If I found out that my child did that, he knows and the other people that know me, know I would have took him to the police myself," Moore said.  

Allison Martin, a spokeswoman with Jefferson County Public Schools, said a Jeffersontown High student approached a security guard after school on Feb. 29, saying another student needed medical assistance in the woods behind the school. 

"The student received assistance from EMS and was transported to the hospital," said Martin, noting that both the district's security and investigations division and the police department are investigating. "Any other other inquiries must be directed to Jeffersontown Police."

Martin did say the students will be disciplined as outlined by the JCPS Code of Acceptable Behavior and Discipline, which states an assault offense at the middle or high school level will result at the minimum of a short-term suspension and or placement in an alternative school.
