Seven New Jersey teenagers were charged on Friday in connection with a series of sexual assaults in a hazing scandal that prompted a high school to cancel the rest of its football season, the authorities said.

Six of the teenagers were taken into custody on Friday evening on charges stemming from attacks on four students in four separate encounters at Sayreville War Memorial High School, in Parlin, Andrew Carey, the Middlesex County prosecutor, said in a joint statement with Chief John Zebrowski of the Sayreville Police Department. The seventh teenager has surrendered to the police, the authorities said on Saturday.

Those charged range in age from 15 to 17. Officials withheld their identities because they are under the age of 18.

The county prosecutor said that on four separate occasions between Sept. 19 and Sept. 29, some of the suspects held the victims, who are also juveniles, against their will, while others “improperly” touched them “in a sexual manner.” One of the victims was kicked during an attack, officials said.
