PS/MS 4 on Fulton Avenue was locked down around 8:15 a.m. while police searched the premisis.
"There was a rumor that a student in one of the schools on the campus came to school with a gun," a spokesperson said. "The principal called a lockdown and police are on the scene."
Officials say a school employee heard one student tell another that he brought a gun to school. That employee went to a school administrator, prompting the decision to lock down the school.
After a thorough search, police found the student and are questioning him. He does not appear to be armed and may have had a toy gun, according to reports.
The investigation is ongoing, but the lockdown was lifted before 10:30 a.m.
