tunnel

I just saw this. I heard a lot of Argentines have cash in safe deposit boxes and in safes. A friend told me that bank safe deposit boxes have been robbed before. What happens when a bank safe deposit box is robbed like this? How do people prove what they have in it...

A tunnel that’s been in the works for a year was discovered in San Isidro, intended for robbing a bank. It’s 3 meters deep and stretches 220 meters long. The tunnel was found by a delivery guy who noticed a metal rod sticking up between the cobblestones and called the police.
