- Schools will be in session Tuesday
- $1,000 reward is offered for information leading to "the arrest of those responsible"
- Students from 3 high schools dismissed after a threatening note found, police say
- The note was found by a teacher at an unidentified school at an educational park
Three Michigan schools went into semi-lockdown after police determined that a note found on a campus was a credible threat, officials said Monday.
The note, which mentioned some form of "student retaliation," was found by a teacher shortly before the school day started Monday, according to Canton Police Lt. Mark Schultz.
Police did not say where the note was found.
By noon, all three schools from the Plymouth-Canton Educational Park were in their "final stages of dismissing students," said Frank Ruggirello, director of community relations.
"We've had a very smooth, controlled dismissal," he said.
Students who normally ride the bus to and from school were taken home after buses arrived, a statement from the school said. Students who were driven to school were taken to a nearby middle school to be picked up, the statement said.
The source of the note remained unknown Monday afternoon, but the Plymouth-Canton community school district said in a message to parents that it is "confident that we can hold classes safely" and that the three affected schools will reopen Tuesday.
"District and police officials will not be satisfied until the person or persons responsible for the threatening note is brought to justice," the district said in the message.
A $1,000 reward is being offered to anyone with information that leads police to "the arrest of those responsible."
While the "suspicious situation" is investigated, school officials are waiting for further instructions from police.
"We listen to police, take direction and do exactly what they tell us to do," Ruggirello said.
The campus of Plymouth-Canton Educational Park encompasses three high schools, totaling about 6,000 students.
