The Banco Central burglary at Fortaleza was the theft of about R$160 million from the vault of the Banco Central branch located in Fortaleza, in the state of Ceará, Brazil, on August 6, 2005. It is one of the world's largest heists. In the aftermath of the burglary, of the 25 people thought to be involved, only 8 had been arrested, and R$20 million recovered, up to the end of 2005. In addition, several of the gang are thought to have been victims of kidnapping, and one member, Luis Fernando Ribeiro, thought to have been the mastermind of the operation, was killed by kidnappers after a ransom was paid. Arrests and recovery of the money, as well as kidnapping and murder of the perpetrators, have been ongoing. One hundred and twenty nine arrests were made, and 32 million Reais were recovered. The Brazilian Federal Police was also able to prevent other burglaries, as shown in the Netflix documentary "3 Tonelada$: Assalto ao Banco Central". The burglary On Saturday, August 6, 2005, a gang of burglars tunneled into the bank and removed five containers of 50-real notes, with an estimated value of R$164,755,150 (about 71.6 million USD at 2005 exchange rate) and weighing about 3.5 tons. The money was uninsured, a bank spokesperson stating that the risks were too small to justify the insurance premiums. The burglars managed to evade or disable the bank's internal alarms and sensors, and the burglary remained undiscovered until the bank opened for business the following Monday. Banco Central is the Brazilian central bank, charged with control of the money supply. The money in the vault was to be examined to decide whether it should be recirculated or destroyed. The bills were not numbered sequentially, making them almost impossible to trace. Planning Three months before the burglary, the criminals rented a commercial property in the center of the city and tunneled 78 meters (256 ft) beneath two city blocks to a position beneath the bank. The gang had renovated the property and put up a sign indicating it was a landscaping company selling both natural and artificial grass as well as plants. Neighbors, who estimated that the gang consisted of between six and ten men, described how they had seen van-loads of soil being removed daily, but understood this to be a normal activity of the business.
