Question: 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 ?
Context: The Hilfspolizei (abbreviated "Hipo"; literally: "auxiliary police") was a short-lived auxiliary police force in Nazi Germany in 1933. Heinrich Baab (born 27 July 1908-?)  was a secretary and Gestapo chief of Frankfurt at the Lindenstrasse station.  The Gestapo (Secret State Police) was the official secret police of Nazi Germany and German-occupied Europe.  After the war in Europe ended, Heinrich Baab received a sentence of life imprisonment in March 1950 for his involvement in the Final Solution as the head of Division IIB2.  He was imprisoned from 1948 to 1973.  On 6 April 1950 he was convicted of murdering 55 Jews from 1938 to 1943 and the attempted murders of 21 Jews, as well as for maltreatment of 29 Jewish prisoners in Frankfurt.  His trial was five weeks long, with 157 witnesses testifying, including some of his victims.  Heinrich Baab sent many of Frankfurt's Jews to camps from the rail station.  Baab's supervisor at the Lindenstrasse station was Oswald Poche.  Before joining the police in 1928 in Stettin, Baab was a locksmith.  Heinrich Baab's SS membership number was 306631 and his Nazi Party number was 1346669. During World War II, the Danish government chose to cooperate with the Nazi occupation force.  Even though this applied to the Danish police as well, many were reluctant to cooperate.  As a result, a large number of members of the Danish police force were deported to Nazi concentration camps in Germany.  The Gestapo established the collaborationist HIPO Corps to replace them. Auxiliary police, also called special police, are usually the part-time reserves of a regular police force.  They may be armed or unarmed.  They may be unpaid volunteers or paid members of the police service with which they are affiliated.  In most jurisdictions, auxiliary police officers are empowered to make arrests for crimes that occur in their presence. Pierre-Marie Paoli, also known as Lamote, (1921 - 1946) was a French agent in the Gestapo.  The Gestapo (Secret State Police) was the official secret police of Nazi Germany and German-occupied Europe. 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"). Special police (also see auxiliary police) usually describes a police force or unit within a police force whose duties and responsibilities are significantly different from other forces in the same country or from other police in the same force, although there is no consistent international definition.  A special constable, in most cases, is not a member of a special police force; in countries in the Commonwealth of Nations and often elsewhere, a special constable is a voluntary or part-time member of a national or local police force or a person involved in law enforcement who is not a police officer but has some of the powers of a police officer. The Gestapo (] ), abbreviation of Geheime Staatspolizei, or the Secret State Police, was the official secret police of Nazi Germany and German-occupied Europe. The Schutzmannschaft or Auxiliary Police (literally: "protection team"; plural: "Schutzmannschaften", abbreviated as "Schuma") was the collaborationist auxiliary police of native policemen serving in those areas of Eastern Europe occupied by Nazi Germany during World War II. " Reichsführer-SS" Heinrich Himmler established the "Schutzmannschaft" on July 25, 1941 and subordinated it to the Order Police ("Ordnungspolizei"; Orpo).  By the end of 1941, some 45,000 men served in "Schutzmannschaft" units, about half of them in the battalions.  During 1942, "Schutzmannschaften" expanded to an estimated 300,000 men, with battalions accounting for about a third of the force.  Everywhere, local police far outnumbered the equivalent German personnel several times (in most places, the ratio of Germans to natives was about 1-to-10). The New York City Police Department Auxiliary Police is a volunteer reserve police force which is a subdivision of the Patrol Services Bureau of the New York City Police Department.  Auxiliary Police Officers assist the NYPD with uniformed patrols, providing traffic control, crowd control, and other major events.
