Photo: A threat Tuesday morning targeting Chaska High School prompted a lockdown that lasted most of the morning and prompted classes to be canceled for the day.

In a series of messages on Twitter that started shortly after 8 a.m., the school said "CHS received a threat this morning, we have taken it seriously and are now working with police."

"Everyone is OK," a tweet reported.
