A threatening message on a whiteboard in an Upper School classroom initiated a Shelter-in-Place protocol for all Cranbrook Schools on the morning of Thursday, May 25, with early dismissal beginning at 10 a.m.

A message was sent to parents at approximately 8:50 a.m. noting, “This is not a drill.”

It went on to say that campus security had initiated their Shelter-In-Place protocol for all of Cranbrook Educational Community, and parents were instructed to not contact the school or their students.

According to Bloomfield Hills Public Safety Captain Dustin Lockard, students and staff are not currently in any danger. He said there was “a concerning image reported this morning, and in an abundance of caution, the schools initiated a Shelter-in-Place and then dismissal. There was no gun or other weapon, and the campus has been determined to be secure.”

He said the police department along with Cranbrook security are beginning their investigation.
