MIDDLE ISLAND - Cellphone video of the aftermath of a senior prank appears to show a Longwood High School security guard slamming a student to the ground.
Senior David Edmond says hundreds of students ran outside to the parking lot at around 10:30 a.m. to play tag, then returned to the school.
Clarence Fenner, also a senior, says a teacher grabbed him by his shirt while in the school's hallway for no reason.
Edmund says he tried to pull his friend away, but claims an assistant principal then started to harass him. He claims the assistant principal raised his hand to hit him.
"I said, 'Go ahead, you're crazy.' Then all I know - I'm in a chokehold, getting choked to the floor, gasping for air," Edmund told News 12.
Edmund says he's been suspended for five days and cannot attend prom or his high school graduation.
In a statement to News 12, Longwood officials said, "Several seniors decided to participate in a senior prank and leave campus. Longwood has a closed campus policy and students were urged not to leave the building by security and administration. A disturbance ensued after students were insubordinate and uncooperative."
News 12 was told that the incident is under investigation. It was not clear if staff members or administrators would face any disciplinary action.
