The Sheffield MA Police Department is located at 10 South Main St
PO Box 186, call 413-229-8522 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 Berkshire County Sheriff's nearby facility.
