Four arrests have been made in connection with what police say was a credible threat to shoot up a Whitmore Lake school building.

The Northfield Township Police Department received information on Tuesday afternoon from Whitmore Lake Public Schools Superintendent Tom DeKeyser regarding a threat that had been made in reference to “shooting up” a school building within the district. Officers immediately began to investigate and deemed the threat to be credible. Four arrests were made between the hours of 6pm and 7:30pm, including three adult males ages 17 -18 and one juvenile male age 16. All of the arrestees are current or past students of WLPS. The juvenile was lodged at the Washtenaw County Juvenile Detention Center and the adults were lodged at the Washtenaw County Jail. A weapon was seized during the course of the investigation.

The case is considered an active investigation and no further comments are being made at this time according to Director of Public Safety William Wagner. He says once the investigation is complete, it will be submitted to the Washtenaw County Prosecuting Attorney’s Office for review and determination of appropriate charges. Whitmore Lake Public Schools were closed today as a precautionary measure. (JM)
