VINELAND — City police are reporting the arrest of four students at three different schools in incidents that occurred the day they returned to class after the Christmas holiday break.

In one of the incidents, police said they charged a 15-year-old Vineland High School South student on charges of having a folding pocket knife stashed in one of her boots.

The other incidents involve a fight between students and an assault on a student and a school security guard.

None of the Jan. 2 incidents are related, local authorities said.

According to police, officials at Vineland High School South on Chestnut Avenue found out about the knife from a student who wanted to remain anonymous. Police said they filed a juvenile complaint of possession of a weapon in a school against the 15-year-old female, who was released to the custody of her mother.

Another incident occurred at Veterans Memorial School on Main Road.

Police said a 12-year-old female student allegedly assaulted another student in a hallway. The 12-year-old also allegedly struck a school security officer who was trying to stop the assault, they said.

The 12-year-old was charged with simple assault, aggravated assault and released to her mother’s custody, police said.

The assault victim and the security guard sustained minor injuries, police said.

The third incident occurred at Landis Intermediate School on Landis Avenue. It involved a fight between three girls ages 14, 13 and 12.

According to police, a school employee saw the fight and told the students to stop the altercation. All three students were escorted to the school’s main office for disciplinary actions, they said.

School officials spoke with all three students, and the 13-year-old and 12-year-old were taken to the Police Department and charged with disorderly conduct, authorities said. The two students were released to the custody of their families, they said.
