ALFRED (AP) — An investigation is underway after a man died while in the custody of the York County Sheriff’s Office.

Authorities say 49-year-old Jeffrey Andrew Noonan of Saco died shortly after going into medical distress at about 6:30 a.m. Sunday. He had been taken for medical treatment the previous day.

Noonan had been arrested last Thursday on a warrant for failure to appear for a charge of unlawful possession of scheduled drugs.

Per protocol as mandated by the state attorney general’s office, the death will be investigated by Maine State Police.

The Maine State Department of Corrections Inspections Division was also notified.
