Hervé Falciani, the French-Italian former HSBC employee who blew the whistle on HSBC and 130,000 global tax evaders in 2008, has been arrested in Madrid on Tuesday in response to an arrest warrant issued by Switzerland for breaking the country’s bank secrecy laws.
Falciani worked as a computer technician for HSBC’s Swiss subsidiary. One day in 2008, he left the office with five computer disks containing what would eventually become one of the largest leaks of banking data in history.
