After several months of investigations, officers from the specialist robbery unit of the National Police have made arrests and broken up a gang of thieves that was breaking into properties without leaving any trace of how they had gained access.
According to sources, the criminals didn’t leave the slightest hint of their presence in the property - they were so meticulous that they left the home as it was when the residents left. Owners were puzzled by having been the victims of a theft without anything being forced. And there were even those who even became suspicious of someone from their household due to the tidy way in which personal effects had been stolen from their home.
With the arrests made in recent weeks, the National Police consider the gang, originally from Eastern Europe, disbanded.
The break-in technique used by this group, which has been revealed by the police, consists of inserting a key with deformable aluminium sheets into the lock, which, with very precise movements, copied the notches and marks of the original key. From this they made a master key that allowed them to open the door without leaving any trace that the lock had been forced, because, in reality, it hadn't.
