In Night, why was Moshe the Beadle forced to leave Sighet by Hungarian police?

In 'Night', the narrator is Eliezer, a Hungarian boy who was 12 years old at the moment and who was living in Sighet. This town was part of Hungary during World War II, at the time this story was set (on the contrary now it is in Romania).

Moshe the Beadle was Eliezer's teacher of Jewish doctrine and, in fact, he was an inspiring and challenging educator for this kid. All foreign Jews were sent out of town by the Hungarian police, including Moshe, as part of the anti-Semitic acts generalized all over the nazi Europe. Hungary was one of Germany's allies during World War II, and obeyed the type of politics fostered by Hitler, contributing to spread attacks against Jews and ejections within its territory.
