The Jamestown NY Police Department is located at 201 East 2nd St, call 716-483-7536 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 Chautauqua County Sheriff's nearby facility.
