PHOENIX -- 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.
The Arizona Republic says Dunn reportedly was yelling at another student about bad behavior and the alleged victim began to laugh.
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.
