KENOSHA, Wis. (CBS 58) -- Police are still trying to figure out who made the threat Wednesday night against Indian Trail High School and Academy in Kenosha.
Students CBS 58 spoke to said they were surprised that a threat would be made against the school, "I'm scared because I just can't think about what would happen if we didn't find out," said Damaris Cazares.
The School District said they were notified about the threat at 11 p.m. Wednesday night and at 4 a.m. Thursday morning made the decision to cancel school.
The threat said they were planning on "shooting up the school" and was posted on Snapchat.
Some students said they didn't know that school was canceled, "I thought I was late today. I was rushing trying to speed on the road and I got here and something felt weird," said Nicholas Wiley.
The School District is still deciding whether or not school will be canceled on Friday as well.
Last week another school in Kenosha Unified School District, Lance Middle School, dealt with a bomb threat but school was not canceled.
