(KMZA)--The reason behind Wednesday's lock-down of the Axtell Public School remains unspecified, but the school district Superintendent says “further information will be made available if and when necessary.”

WIBW-TV is reporting the lock-down was put in place after a threatening note was found in the school, with a student arrested in connection with the threat.

However, MSC News has not independently confirmed that report with the Marshall County Sheriff's Office.

In a news release issued early Wednesday evening, Prairie Hills USD 113 Superintendent Todd Evans explained that once the lock-down was put in place around 1:15 Wednesday afternoon, law enforcement was called to the school.

In the statement, Evans says all students and staff remained throughout the afternoon, during the lock-down, with school dismissed at the usual time.

Noting that the district's primary goal is the safety and security of the students, Evans voiced appreciation for the support of law enforcement, parents, and the community.

The Marshall County Sheriff's Office told MSC News Wednesday afternoon the investigation is continuing, which is being assisted by the Kansas Highway Patrol
