The Galveston TX Police Department is located at 601 54th St
PO Box 17251, call 409-765-3702 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 Galveston County Sheriff's nearby facility.
