A German Jew I am researching was arrested in Germany some time around 1935. He was released some time thereafter, and emigrated to the United states in 1936. I am wondering where to look for such arrest records. This event took place most likely in Kirchheimbolanden, in the Pfalz.
Since I don't know much about the structure of the German Police in that era, nor about their possible cooperation with the Gestapo, I think the best place to start is the site of the BundesArchiv in Berlin.
