John Mellencamp's 20-year-old son is facing a charge of underage drinking following an incident in Indiana earlier this month (Jul14).

Hud Mellencamp was allegedly caught consuming alcohol by Monroe County police on 10 July (14). He has been summoned to appear in Monroe Circuit Court for a hearing on 25 September (14).

It's the latest legal woe for young Mellencamp - he and his 19-year-old brother Speck are heading to trial over accusations they beat up a man last summer (13).

The boys, who are free on bail, are due to attend a pre-trial conference over the felony battery charge in Monroe County on Thursday (24Jul14).
