Whistleblower in HSBC tax evasion scandal arrested in Spain
A former HSBC employee convicted of leaking account data that led to a tax evasion scandal has been arrested in Madrid on a warrant issued by Switzerland, Spanish police said.
French national Herve Falciani was sentenced in late 2015 to five years in prison for economic espionage.
A Swiss court also convicted him of illegally obtaining data, breach of business confidentiality and of bank secrecy.
Some regard Falciani as a crucial whistleblower whose more than 100,000 records on prominent clients of HSBC Private Bank (Suisse) SA sparked a global wave of tax evasion probes.
The former IT specialist gave the data to French tax authorities in 2008, after some of it emerged in press reports.
France shared it with Spanish authorities and other governments. As a result, the Swiss subsidiary of HSBC has been investigated in several countries for allegedly helping wealthy people around the world dodge taxes.
Falciani moved to Spain and cooperated with authorities there in some of the probes. He was arrested in Barcelona in 2012, but Spain's National Court denied a Swiss request to extradite him on the grounds that breaking secrecy laws was not subject to prosecution in Spain.
The arrest on Wednesday, nearly two years after Falciani's conviction was made final by Swiss courts, comes as Spain seeks the extradition from Switzerland of Marta Rovira.
The prominent Catalan separatist politician is considered key in the Spanish region's illegal independence bid.
Lawyer Marc Henzelin, who represents Falciani in Switzerland, said his legal standing was even more favourable now than after the conviction.
He said he had "no reason to believe the Spanish authorities will accept an extradition".
He said Swiss authorities issued a request to Spain for Falciani's extradition on March 21, long after his conviction.
Mr Henzelin noted a "hypothesis", which he could not confirm, expressed by some that the arrest could be connected to a "sort of deal" between Spain and Switzerland over a possible transfer of Catalan separatists who are currently on Swiss soil and wanted by Spanish authorities.
"I'm not able to verify that, but frankly if it were the case, I would consider that rather odious," he said.
"It's not in the tradition of Swiss justice to do such a kind of bargaining. It seems to me it's more the habit of Russia and countries like that."
X.net, a platform of internet activists that cooperated with Falciani in some corruption investigations, has criticised the arrest.
"Whistleblowers of corruption used as exchange currency. What justice is this?" the platform said in a tweet.
