Students sent home after possible school threat

CANTON TOWNSHIP, Mich. (AP) - Students were being sent home early at Plymouth-Canton Community Schools' high schools after police say a note containing a possible threat was found.

Police in Wayne County's Canton Township said in a statement that a "note indicating possible retaliation" was found before the start of classes at the suburban Detroit high school complex. Details of the note containing the "possible threat" weren't released by police.

Police say the high schools went into semi-lockdown and students were being sent home out of an abundance of caution. An investigation was under way.

The district announced the early dismissal for students at the Plymouth-Canton Educational Park on its website.
