Threats to John Young Middle school have been addressed by the school.
Principal Mike Fisher sent a letter to families about the three separate threats to Mishawaka middle school.
He says that there is no current threat to the students and staff.
Police say that last week a juvenile posted a picture of a knife on Snapchat warning students not to come to school.
Fisher said that the school takes all matters of school safety seriously, even if the threat is a joke.
