What was the official secret police of Nazi Germany and German-occupied Europe that established a Danish auxiliary police corps  when the Danish civil police force was disbanded and most of its officers were arrested and deported to concentration camps in Germany ?
HIPO Corps The HIPO Corps (Danish: HIPO-korpset) was a Danish auxiliary police corps, established by the German Gestapo on 19 September 1944, when the Danish civil police force was disbanded and most of its officers were arrested and deported to concentration camps in Germany. The majority of HIPO members were recruited from the ranks of Danish Nazi collaborators. The word "HIPO" is an abbreviation of the German word "Hilfspolizei" ("auxiliary police").
Bundesgrenzschutz Bundesgrenzschutz (BGS; English: Federal Border Guard ) was the first federal police organization in West Germany after World War II permitted by the Allied occupation authorities. In July 2005, the BGS was renamed "Bundespolizei" (Federal Police) to reflect its transition to a multi-faceted police agency. This was controversial due to the German constitution expressly granting law enforcement power to the states. The fact that the border guard function was so limited allowed its formation notwithstanding this restriction, however in the modern day it has become a fully fledged police force.
