GILBERT, AZ - Authorities say no criminal charges will be brought against a Gilbert High School math teacher accused of assaulting a student last month.
Daniel A. Dunn was placed on administrative leave by the school after he allegedly slapped a 15-year-old student in the face with the back of his hand on April 17.
Police interviewed several students who witnessed what happened, including the alleged victim.
He says Dunn was standing next to his desk and arguing with a student, and when the victim started laughing, he says Dunn slapped him in the face, and said, "I told you to shut up."
The student was not hurt and immediately reported the incident to school officials.
Gilbert police arrested Dunn and forwarded the report to Town Prosecutor Lynn Arouh.
She announced Wednesday that the 67-year-old Dunn won't be charged in the case.
There's no immediate word from Gilbert Public Schools as to whether Dunn was reinstated from his administrative leave.
Dunn was Gilbert High's football coach from 2009 to 2011.
