From IP Germany:
1-Information was sent to Warsaw for them to trace and interview the Polish couple whose personal and travel details were communicated.

2-Information collected by the German authorities from Air Berlin indicated that Poles used this connection route because there were no direct flights to/from Portugal/Faro and no other carriers offered low prices. Flight manifests could not be obtained from the airline after-hours and the documents obtained were incomplete, but of the 82 reservations (either through Internet or direct with Air Berlin), data for 30 other people could be obtained from other travel agents. Air Berlin documents showed no suspicious reservations pertaining to children.

Using the “PAX-LIST” (passenger list), persons in seats around the KROKOWSKI couple were shown pictures of Madeleine and all stated that that couple was not accompanied by any child.

From IP Warsaw:
– At 07h10 this morning (6 May) the couple were interviewed in their home apartment, which was searched and the missing child was not found. After arriving in Berlin they left by train at 21h22 arriving home this morning at 06h45.
