Expanded border controls introduced temporarily for the championships prevented 900 people from entering the country between June 7 and June 13, the Sunday paper said.

The expanded controls include Germany's borders with Denmark, France and the Benelux countries, with travelers from within the Schengen area - who can usually move freely within that area - expected to be checked at airports and ports

"This shows that our measures are working. Above all, we want to identify and stop violent criminals early," Interior Minister Nancy Faeser told the paper.
