They want to go to Germany or other countries and once they are processed (ID check and fingerprints collecting), they are free to go, if they want to resume their journey. Five families and several individuals asked for asylum, because they have ran out of money and some have friends here.
Also another tidbit from migrant camps, some of them have a lot of money with them and they are asking policemen if they can keep eye on their belongings, when they go under shower and to dinner, if they have only one or two fellow travelers with them. Bigger groups have their own 'guards' and they take turns in guarding their belongings. And cops on the border were listening to migrant stories about Germany, where they will get free housing and 2000 of help each month.
Austria received almost 30.000 migrants this weekend and more than 700 asked for asylum. Vast majority is going to Germany.
