A threatening note near a classroom led to the lockdown at Naperville Central High School.Students were kept in their classrooms as police searched the buildings in what officials called a 'soft lockdown.'

Police said the note described a threat with enough detail that it deserved an immediate response.

Late Friday afternoon, the students were allowed to go home.
