Classes are expected to resume on schedule today at Illini Central High School in Mason City, after a lockdown yesterday following a report of a student with a gun.
Students were kept in classrooms for several hours as the building was searched by SWAT teams.
Authorities still have not said whether a weapon was found, but someone was taken into custody for questioning.
Some parents are angry that they were not getting official statements about what was happening inside the school, and were only getting information from text messages and Facebook posts by students inside the school.
