CHESTER, Pa., (CBS) – It’s a story you saw first on 3 – A vicious beating inside a local high school and a cell phone camera captured it all.

On Wednesday, police arrested five students they say were involved in the fight at Chester High School. Police say even more arrests could be coming.

The video shows a group of students not only throwing punches, but using chairs to attack and beat a 16-year-old boy inside the library of Chester High School. According to police, among the arrested students is 18-year-old Edward Stanley who appears to have recorded the fight on his cell phone and later posted the video on Facebook.

“It’s terrible. It’s something that is ungodly. It’s like the devils were in there.”

A man who identified himself as the father of the 16-year-old victim had no idea the video existed until we showed it to him. He says his son, who now has four stitches in the back of his head, moved to Chester from Delaware, just three months ago. He asked to remain anonymous.

“The kids are really taking over the school there. I think security really needs to be stepped up in there.”

Chester Mayor John Lindner said, “We’re going to treat each incident individually. We’re going to investigate it thoroughly and obviously we don’t like having our school district painted in this color or our city in this color.”

Chester Upland School District Receiver Joe Watkins added, “Obviously in an ideal setting, we would have a situation where this would not happen, where this could not have happen and we’re going to investigate and find out what happened.”

Authorities maintain their investigation is far from over adding that Stanley along with four other students including two 16-year-olds may not be the only ones charged in this case. So far, all five students have been charged as adults with Simple Assault, Aggravated Assault, Conspiracy, Robbery, Recklessly Endangering, Terroristic Threats and Possession of Instrument of a Crime.

The victim’s father meanwhile hopes everyone responsible will be held accountable.

“You think it’s all fun and games but it isn’t no game out here and you think you’re getting away with it but you’re not.”

Police tell us the incident happened Tuesday afternoon. They confirm they were not notified by the school but rather by a student Tuesday night after the student saw the video on Facebook.

When asked how this incident went undetected by a teacher or staffer and unreported by the school, Watkins said, “We don’t know that yet but we’re investigating and the proper action will be taken when we know.”
