The Greenville ME Police Department is located at 7 Minden St
PO Box 1109, call 207-695-3835 to find out about new arrests or outstanding warrants. This is a police jail for housing inmates immediately after their arrest. Local police departments are not built for long-term inmate holding, they are for very short-term stays because there are not enough cells. There are no visits, commissary or phone accounts available to the offenders.
If they are to remain incarcerated, it will be most likely to the Piscataquis County Sheriff's nearby facility.
