Greece Police say they have several people in custody following an incident at Greece Odyssey Academy on Friday.
Greece Police Chief Patrick Phelan says there will be a press conference at 2 p.m. Tuesday with more information.
Phelan also took the opportunity to debunk rumors that there were threats to Greece Schools on social media.
He says no threat of any kind has been made.
However, he says officers will be placed in high schools Tuesday to make parents and students feel safer.
