Naperville North High School is having to cancel classes for the second time in under thirty days due to a threat against the school.
A message from school officials first placed the school on a soft lockdown Friday morning at around 9:20 followed by another announcement, about an hour later, that said classes were to be canceled for the rest of the day.
Naperville Police were at the school. Students were not allowed access to their lockers on the way out.
School officials did not say what kind of threat the school received.
