A Unionport school went into lockdown Friday after police say a 13-year-old student arrived armed with a knife.

Police say the 13-year-old student with a knife ran wild in the hallways. Kindergarteners through eighth graders at P.S. 194 were put on lockdown.

It happened shortly before 11:20 a.m. at the K through 8 school, which went into lockdown for 10 minutes, according to the Department of Education.

Police say it might’ve been sparked by bullying. The girl eventually put the knife down before anyone was injured.

Classes were later dismissed one by one, and the students were sent home with a letter.

The Department of Education says staff, school safety agents and police responded and that guidance counselors will be available for students.

Police say the 13-year-old student was taken to North Central Bronx Hospital for an evaluation.

The DOE says all protocols were followed and that it is working with the NYPD on any follow-up action.

Parents say they were initially worried over the safety of their children but are grateful that there were no injuries. However, they also called for more school security before this happens again. One parent said the school never notified him and that he heard about it from his daughter.
