The school's police resource officer was notified about both incidents, and Central Middle School, 500 E Ninth St. was put on lockdown while officers searched for the man.
His father told police his son was at the Edmond Racquet Club, 425 Lilac Drive, where Moon was arrested.
Moon was a student in Edmond Public Schools from August 2005 through August 2012, and graduated from Edmond Memorial High School last spring, Parks-Schlepp said.
He played tennis for the school from ninth grade until March 2012 during his senior year. Parks-Schlepp would not say why he stopped playing tennis for the school short of his graduation.
