'It's frustrating': Parents say they were left with many unanswered questions following 'soft lockdown'

A suburban high school just west of Chicago went into a "soft lockdown" after a gun was taken from a student Friday morning. 

The superintendent's office for J. Sterling Morton High School District in Berwyn said the high school was secure and instruction continued during the lockdown and police investigation. 

Berwyn police say the student that had the gun did not make any threats and no injuries were reported.

The incident is currently under investigation by the Youth Investigations Unit. The Berwyn Police Department says they do not believe there are any threats to Morton West High School at this time.

The school sent out a statement informing parents of the lockdown, but not its cause, around noon.
