THE police case against the prime suspect in Madeleine McCann’s disappearance appeared close to collapse last night.
An ex-pal of Christian B, 45, made a damning statement against the convicted child sex fiend.
But sources close to the German probe say their key witness is “wobbling” and threatening to stop helping.
Cops hope to nab Christian B over Madeleine, who vanished in 2007 aged three.
A damning statement by Helge B – an old pal of Christian B – has become a cornerstone of the German-led police case.
