Who is arrested along with the annex residents?

That would be Anne Frank, her sister Margot, her father, Otto, her mother, Edith, the Van Pels, Auguste, Hermann, and Peter, and Pfeffer Fritz. The people who were arrested that weren't hiding in the Secret Annex but associated with it were Mr. Kugler, and Mr. Crowler.

Victor Kugler and Johannes Kleiman were arrested and jailed at Amersfoort. This was a penal camp where enemies of the regime were interred.
