Police admit they have lost 155 DVDs of sexual abuse - and did not make backups

German police have admitted to losing almost all the incriminating digital evidence against two paedophiles accused of sexually assaulting least 31 children as young as four, allegedly raping their victims more than 1,000 times.

Main suspect Andreas V., 56, and his campsite neighbour Mario S., 33, allegedly sexually assaulted dozens of children at a rundown caravan park in Luegde, a town in the western German state of North Rhine-Westphalia.

The case has shocked Germany, but despite the extremely serious allegations, police are now saying that almost all the incriminating digital evidence has gone missing - and that they apparently forgot to make backups.

The discovery of the massive abuse case has shocked Germany and left the public, as well as prosecutors, wondering how it could have dragged on for so many years without the authorities doing anything to stop it.

To the further shock of Germans, the authorities have now announced that a suitcase containing 155 critical pieces of evidence which have not yet been reviewed has gone missing.

The suitcase reportedly contained 155 CDs and DVDs from Andreas V.'s trailer which have gone missing from the police station in the Lippe district.

Only three of the 155 data carriers with a total of 0.7 terabyte of data on it have so far been reviewed.

Interior Minister of the German state of North Rhine-Westphalia Herbert Reul said that 'also in the analysis it came to serious technical errors' as cops forgot to make copies of all the data carriers which is a normal procedure if such evidence is received.
