Who polices Sprague
Sprague has no municipal police department and is covered by Connecticut State Police Troop E, so an arrest in town is a state police arrest.
Baltic is the village centre of Sprague. If the paperwork you were given says Baltic rather than Sprague, that is the same town, the same coverage, and the same court. It is a village name, not a different jurisdiction.
Where your case goes
Sprague cases are heard at Norwich Superior Court, GA 21, a short way south at 1 Courthouse Square. The court page covers the parking, which is mostly paid and on the street downtown.
Let go by the trooper, you keep the date you were handed. Kept overnight, you are in court the next business day.
After the arrest
The trooper either releases you on a written promise to appear, sets a bond, or holds you for court the next business day. Released, the date is on your paperwork; held, the judge revisits the bond at the first appearance. The arrest page covers booking, the bond and bail page covers the money.
Family violence is the exception to all of it: court the next business day whether or not you were released, and a protective order issued there.
Before any of that, stop discussing the case, and treat calls from holding as recorded. The arraignment page covers the first appearance and the what to expect page covers the months that follow.
Common charges in Sprague
The Sprague docket at GA 21 is small: DUI, drug possession, assault, domestic violence and family violence, and larceny and shoplifting. A first offense frequently qualifies for a diversionary program, and most of those can be used only once, which makes the timing of the application a real decision.
