The student who allegedly threatened two fellow students with a knife has been formally charged.
Jason Winowiecki, 17, was charged with assault with a dangerous weapon in a weapons free area (school).
Winowiecki is being held on a $250,000 bond in the Leelanau County Jail.
He has been referred for a competency exam.
Winowiecki was arrested after witnesses said he grabbed a 15-year-old student from behind and held a open lock blade against his neck after the student danced with his sister at the school dance Saturday night.
The Leelanau County Sheriff also reported another student later told the suspect that "it wasn't right" to which Winowiecki responded by opening his coat and threatening that student with the knife as well.
Winowiecki has been suspended from school pending a state mandated hearing that will include those who has investigated the case as well as school officials and parents.
Suttons Bay High School principal Raphael Rittenhouse said Winowiecki did not plan to hurt anyone and that the situation was a "prank."
??It was something that was done to make the other student aware that they had this knife with them at the dance. It wasn??t designed to act anything out," said Rittenhouse. "It was a really poor decision on that student??s part to get the other student??s attention and carry out something completely different from trying to do what wound up being a very unsafe activity with somebody that he knew."
