The mystery donor who paid the £1,300 court fine that has paved the way a key suspect in the Madeleine McCann's case to walk free has been identified as a former police officer.
The woman, who has not been named, claims to have formerly been involved in wire-tapping the jail cell of paedophile Christian Brueckner, The Sun reported.
Brueckner is the main suspect in the unsolved disappearance of three-year-old Madeleine McCann, who vanished from her family's holiday apartment in Praia da Luz, Portugal, in May 2007.
The 48-year-old is currently serving a seven-year jail sentence in Germany for the 2005 rape of an American woman, then 72, in the same Algarve resort where Maddie went missing.
The woman who paid the fine is said to be a former member of the BKA, the German equivalent of the FBI.
