At 5:11 p.m. on Saturday, an officer was working a private detail at Skyline Chili, 1 East High St, when he observed a male walk into the restaurant with an open can of Natural Light beer.  The officer approached the male and noticed his breath had an alcoholic odor.  When the officer asked the male how old he was the male replied that he was 19, and asked the officer to please not inform his parents that he had gotten into trouble.  The male was arrested and taken to OPD where he stated that he was actually 18 years old and that he often forgets his age.  The male was charged with Offenses Involving Underage Persons and transported back to his dorm room at Havighurst Hall.  When the officers returned to OPD they noticed from his booking information that the male was actually only 17 years old.  His parents were contacted and provided with information about the arrest.
