On Thursday, the Newburgh elementary school was placed on a planned modified lockdown after the drugs were found on school grounds, according to Glowacki.

"During the modified lockdown, scholars remained in their classrooms while the City of Newburgh police department conducted a sweep of the building with their K-9 unit. The sweep was scheduled as an extra precaution to ensure no additional marijuana items were on school grounds," Glowacki adds.

No items were found during the sweep.

"Immediately following the planned modified lockdown and scheduled sweep of the building, our social emotional team was available to speak with classes or students that had questions or needed support in processing any emotions," Glowacki wrote.
