Probably from this SI article:
On Aug. 29, 1984, shortly before his junior year at Michigan State, Skiles was driving his car near Plymouth when a policeman pulled him over. The policeman said that he found at least one small vial containing a small quantity of cocaine and a plastic bag containing marijuana in a gym bag in the front seat. Skiles's initial explanation was that his roommate had hidden the drugs in his bag. Then he said he didn't know how they got there. He was arrested and released pending trial. Three weeks later, near East Lansing, Skiles was arrested and charged with driving while intoxicated.
In April 1985, Skiles pleaded guilty in Plymouth to a misdemeanor charge of marijuana possession. The felony cocaine charge was dropped. He received one year's probation, one of the conditions of which was that he not drink or set foot in a bar. He also paid a fine of approximately $100 and worked 120 hours in a home for the aged. In Michigan he pleaded guilty to a reduced charge of impaired driving. There he paid about $300 in fines and spent nearly three days in jail.
Then, in the early hours of Nov. 7, 1985, 2� weeks before the start of this basketball season, Skiles was arrested again, this time in East Lansing, and charged with driving while intoxicated. There was a public outcry. Detroit News columnist Corky Meinecke wrote, "[ Skiles] has worn out his welcome. He is an embarrassment to his university, his coach, his teammates and himself."
