Germany's new interior minister, Horst Seehofer, wants to open the first so-called "anchor center" in the autumn.
Many migrants are to be housed there from arrival to deportation. But police are skeptical.
Interior Minister Horst Seehofer is pressing ahead with his "masterplan" to speed up deportations of asylum seekers and refugees and streamline asylum procedures.
Deputy Minister Stephan Mayer told German daily Süddeutsche Zeitung that opening a so-called "anchor center" in time for the Bavarian state elections in mid-October had "the highest priority."
Under plans presented by Seehofer when he took over as interior minister, these so-called "anchor centers" are designed to house asylum seekers from their arrival in Germany until their possible deportation. The first one is likely to be built in Bavaria.
