Robbers spent a million dollars on a tunnel to a bank vault. They were detained when almost everything was ready

In Sao Paulo arrested 16 suspects who were going to rob the Bank of Brazil.

To get to the bank's vault, the criminals dug a tunnel 600 meters long, reinforced it with metal racks and conducted electricity into it. TV channel Globo reports that they spent about 4 million Brazilian reais (about $1.3 million) on preparatory work.

According to the police, the criminals planned to complete the preparations for the robbery by Wednesday, October 4. They were detained as a result of the operation carried out on Monday.

The State Bank of Brazil is the largest and oldest in the country. The robbers were going to take out of it 1 billion reais (more than 300 million dollars). If successful, this robbery would be the largest in Brazilian history.
