In August, 2005, a gang of robbers tunnelled their way into a Brazilian bank vault in a heist straight out of the movies.

Three months before, the thieves had set up a landscaping business, Grama Sintetica - or Synthetic Grass, from a house close to the Banco Central in Fortaleza. But it was a plot to disguise their real activity.

Working in shifts, they dug an 80 metre tunnel from the house, under a neighbouring street and into the vault before escaping with more than 160million reais, then the equivalent of $70million.

Antonio Celso Dos Santos, then a federal police chief, was one of the detectives who tracked down the gang. He spoke to Jane Wilkinson about the investigation.
