A Mesa high school student won't be prosecuted on a felony charge after police say he exposed himself in a football team picture that ended up in the school yearbook.

The Maricopa County Attorney's Office announced Wednesday that 19-year-old Hunter Osborn won't be prosecuted on a felony charge of furnishing harmful items to minors.

The misdemeanor charge of indecent exposure was returned to Mesa police for further investigation.

Police say all parties involved no longer seek prosecution and the case will be closed.

Osborn was arrested after police were alerted Saturday to a Red Mountain High School team photo showing Osborn exposing his penis through the top of his waistband.

Police say Osborn admitted to the prank, said he did it on a dare and was disgusted by his actions.
