One of the four Hoboken High School students charged in a sexual assault of a 17-year-old girl at the school last month recorded video of the incident as the girl was forced to perform a sex act on another student, the Hudson County Prosecutor's Office said.

Four male students allegedly took part in the Nov. 30 incident, authorities said. A hallway surveillance camera recorded the girl student being pushed into a room during school hours, prosecutors said.

Once in the room, prosecutors say, the girl was forced to perform a sex act on a 17-year-old, with two 16-year-olds and an 18-year-old present.

The 17-year-old student has been charged with aggravated sexual assault and kidnapping, both first-degree crimes.

Neither he nor the two 16-year-olds have been identified because of their ages, prosecutors said. All four were charged on Nov. 30, the prosecutor's office said.

The 18-year-old, identified as Amir Goodwin, was charged with possession of child pornography and distribution of child pornography after he videotaped the incident on his smart phone and then forwarded the video, the prosecutor's office said. He was also charged with criminal restraint at that time, the prosecutor's office said.

Goodwin was again arrested Dec. 12 on additional charges of aggravated criminal sexual contact, criminal sexual contact, conspiracy to commit kidnapping, and conspiracy to commit aggravated criminal sexual contact, the prosecutor's office said.

Hudson County Prosecutor Esther Suarez issued a statement calling the incident "deeply disturbing on so many levels," and promising a thorough investigation and prosecution "to the fullest extent of the law."

"The ages of all the alleged individuals involved, the acts alleged, and the brazenness of where they took place," Suarez said. "Children in school need to feel safe and parents need to feel confident of their safety."

Goodwin's lawyer, Adrienne Edward, said Goodwin was not detained following his initial arrest, but later was placed in the Hudson County Detention Center following his arrest on the additional charges. He was then ordered released following a detention hearing on Tuesday by Superior Court Judge Mark Nelson, who rejected a motion by the prosecutor's office to continue holding him, Edward said.

Edward declined to comment on the charges against Goodwin, other than to emphasize that he had not been charged with sexually assaulting the victim.

"As it relates to the aggravated sexual assault charge, my client was not the receiver of the sexual act," Edward said. "The recipient of the sexual act was one of the juveniles, and not my client."

Edward said her client was a junior at Hoboken High School, where he played on the varsity football and basketball teams. She said Goodwin told her that some colleges had scouted him as a potential basketball recruit, but that he was now concerned that the incident would sour the schools on him.

Edward said her client and the three other defendants, as well as the victim, have not been in school since the incident, but rather have been receiving home instruction.

Hoboken Superintendent of Schools Dr. Christine Johnson issued a statement Wednesday afternoon.

"The alleged victim reported the incident to a counselor," the statement read. "The counselor immediately brought the alleged victim to the principal and to a Hoboken Police Department School Resource Officer. The Hoboken Police contacted Prosecutor's Office within minutes due to the nature of the allegation."

Johnson further stated that the high school has "a comprehensive School Based Youth Services Center and qualified staff," available to respond to students' needs in the wake of the incident.

"Hoboken High School takes these allegations seriously and assures families that the school environment is safe and conducive to learning," Johnson stated. "The Hoboken High School administration has reviewed processes and protocols, and will deliver a host of educational programs for both students and families on topics related to this allegation."
