Assistant State's Attorney Jeffrey Wennar said a videotape camera caught Andre Wells, 16, of the 12900 block of Boggy Trail Way in Germantown, in action. Such cameras are installed in all Montgomery County high schools.

The prosecutor stood before Judge Stephen P. Johnson, drew his arm back and threw a punch into the air to simulate the blow that injured a 10th-grade male student Thursday.

The punch landed "square on the jaw, sending him to the floor in a semi-conscious condition with a fracture on the back of his head," Mr. Wennar said.

The injured student was hospitalized. On Friday, his condition was listed as fair. Mr. Wennar said the state is waiting for the results of a CAT scan and neurological test of the injured student.

Noting that Mr. Wells, who is charged as an adult, is 6 foot 2 inches and 270 pounds and the victim, 5 foot and 8 inches and 160 pounds, Mr. Wennar said the student charged with first-degree assault should be detained. "He is a danger to the community."

Mr. Wells told officials he is a member of a Montgomery Village gang. The gang calls itself the Montgomery Village Mob.

The prosecutor asked for a $75,000 full cash bail. Judge Johnson raised bail from $10,000 to $50,000.

Mr. Wells' mother, Tia, wept as she stood to ask the judge to release her son to "come home and live with me." He has been living with his father.

She said her son is on probation for conviction of an assault on the street four years ago, but she convinced him to turn himself in Thursday evening, about seven hours after the mid-morning attack in a hall outside the school cafeteria.

"He is tall and he is strong," Public Defender Catherine Woolley said. "He doesn't know the strength of his own force. This was one blow. It wasn't a melee. Nothing further ensued."

Mr. Wells practically filled the TV screen picturing him from the Detention Center for the closed-circuit hearing. Mr. Wennar rejected a suggestion that Mr. Wells be moved to the Noyes Childrens' Center.

"He's outgrown Noyes," he said. "He was a predator."

The charging document states Mr. Wells told Police Detective William J. Peacock "he lost his temper and hit the victim."

Montgomery County Police said the injured student was involved in a fight between two sophomores and two juniors that was fueled by a dispute the day before.

The injured student, who is white, was struck by Mr. Wells, who is black, after the white student called him "a racial name," according to students at the school.

Several ninth-grade students who witnessed the fight said the injured student is a nice kid, but "doesn't know when to keep his mouth shut."

Anastasia Romero, a student, said the incident started Wednesday, when a black student asked a white student to turn down the speakers in his backpack. In response, she said, the student turned the music up, but they "let it go."

On Thursday, the white student who got hit "said a racial slur" when he was trying to break up a fight between another white student and a black student, Anastasia said.

Anastasia said the student's sister, who is in ninth grade, had to be held back during the brief fist fight.

"They let her stay with him after he fell," she said. "She was kneeling on the ground and talking to him."

Anastasia said when the injured student fell to the floor and was bleeding from his mouth, "it was scary."

Cody Collins, another student, Thursday said the injured student "yelled the N word to a black student yesterday, but they walked away. Today the black kid got a group of black friends together."

One of many students who gathered to watch the fight, Cody said they were always fighting. But this time, he said it looked like the injured student's jaw had been dislocated.

"We were just standing there, like in shock," Cody said. "The whole lunchroom came out and watched. It was shocking. He just fell and started bleeding."

Cody said the school has fights about once a week, but usually just involving pushing.

"It was always just black kids fighting," he said. "This is the first time it's been a white kid and a black kid."

School system spokesman Brian Edwards said the two students who attacked the others will be suspended.

The school security staff person at the school, Scott Davis, is a certified emergency medical technician who made the call to have a helicopter take the injured student to a hospital.
