Harrodsburg Police Lt. Chad Powell told The Associated Press on Thursday that the warrant stems from an incident Saturday after a performance by the Mickey Hart Band at Terrapin Hill Farm in Harrodsburg.
Powell says that the investigation is ongoing and that the paperwork could not be released. Mercer County Attorney Ted Dean was in court Thursday morning and did not immediately return a call seeking comment. Email messages sent to Hart's management were not immediately returned Thursday morning.
Details of the incident remain unclear. Hart played with the Grateful Dead from 1967 until 1995.
The website TMZ.com first reported the incident.
