The 2005 Banco Central burglary in Fortaleza, Brazil, was once recognized by Guinness Book of World Records as the world’s greatest bank robbery.

To pull it off, a 25-member gang set up a fake landscaping business. They spent three months digging a 256-foot tunnel that led up through the bank’s vault floor.

Once inside, they stole several containers that held 160 million Brazilian real (worth $71.6 million in 2005). Only eight people were arrested, and just 20 million real was recovered
