WOONSOCKET — One day ended at Woonsocket High School with a student argument and the next began with a fight. In between, a student threatened to blow up the school.

Five students, including four girls, were arrested between Thursday afternoon and Friday morning, all on charges of disorderly conduct, police said.
It all began about 2:40 p.m. Thursday, just after dismissal, said Patrolman John Raymond, the school resource officer. A group of about 150 students was lingering in the Times Square area of the school after the bell, and administrators were urging them to leave the building.
Suddenly, said Raymond, he noticed one agitated girl walking past him, complaining that another student had harassed her. A moment later, a group of girls was trying to push another female into a classroom to keep her from fighting.
Yelling and screaming, the girl violently resisted the efforts to get her into the classroom, according to police reports. Eventually, Raymond said the girl was isolated and told to remain seated. The police later took two sisters into custody, ages 15 and 17.
Raymond was in the Times Square area of the school again about 8 a.m. the following morning when he saw the two other girls throwing punches at each other and pulling each other’s hair, the officer reported. Both girls, ages 15 and 16, were taken into custody.
They later told Raymond the fight stemmed from the same argument that had broken out at dismissal time a day earlier, but they did not say what it was about.
There was yet another student arrest on Thursday, although it was unrelated to the others. A 16-year-old boy was charged with disorderly conduct after he threatened to “blow up” the school on Saturday, police said.
Raymond said he arrested the boy after a social worker from the state Department for Children, Youth and Families summoned him to a truancy court in the cafeteria about 3 p.m. The social worker told him she overheard the boy make the threat in a conversation with another student.
The boy later told police he made the remark because he was upset that the truancy court judge told him he needed a doctor’s note to have his absences excused.
