Danske Bank whistleblower says he raised alarm four times

The Tallinn branch of Denmark's Danske Bank is implicated in a massive alleged money laundering scheme

A whistleblower who uncovered a massive alleged money laundering scheme at Danske Bank's Estonian branch told a Danish parliamentary commission Monday that he had notified his superiors four times about suspicious transactions but no action was ever taken.

"It's fundamentally unclear to me ... why the executive board didn't take action," Howard Wilkinson, the British former head of the lender's market business in the Baltics, told parliament's Business, Growth and Export Committee.

More than 1.5 trillion Danish kroner (201 billion euros, $235 billion) transited through the Estonian subsidiary of Danske Bank between 2007 and 2015, according to an outside law firm that carried out a probe for Denmark's largest lender.

Danske Bank has said it is impossible to say how much of the gigantic sum was dirty money, but has admitted that many of the suspicious transactions could be "criminal".

Of the around 15,000 accounts under investigation -- which Danske Bank closed in 2015 -- 6,200 are considered suspicious and most of them have been brought to the attention of the authorities.

The bank has been unable to specify exactly where the money came from. It has said 23 percent of the incoming funds were from Russia.

In his whistleblower report, Wilkinson, who was head of Danske Markets in the Baltic from 2007 until his resignation in 2014, described how the Estonian branch handled customers associated with top Russian politicians and companies based in Denmark.

"We're not only talking about dirty money going through Danske in Estonia, there are two other Danske units involved, Lithuania and Denmark," Wilkinson told the committee.

"The money moved from left to right and no one really knows where all of this money really went."

- Ignored warnings -

The bank was warned for the first time in 2007, but it only began to address the problems in 2013, when Wilkinson wrote a report to Danske Bank management to address the problems.

Wilkinson on Monday compared whistleblowers to smoke detectors.

At Danske Bank, "the smoke detector went off four times, there was a huge fire. The smoke was filling all the corridors. Not only did the bank ignore the smoke detector, but the bank actively tried to switch the smoke detector off."

He called for a "formal investigation (into) how (Denmark's) Financial Supervisory Authority regulated Danske Bank in relation to Estonia from 2007."

Also speaking before parliament, the bank's interim chief executive, Jesper Nielsen, acknowledged there had been a "lack of focus and understanding about the scope of the problem".

But he reiterated the bank's position that there was nothing to indicate that Danske employees had been involved in any wrongdoing.

Wilkinson said he knew more details but was prevented from telling all because of a confidentiality agreement he signed with the bank.

He said he feared for his own well-being after coming forward.

"I'm not here doing any names. Priority one: safety. Priority 2: not being arrested. Priority three: not being sued. Priority 4: telling you what I can."

The money laundering allegations are linked to a fraud case exposed by the Russian lawyer Sergei Magnitsky, who was jailed in Russia after he revealed the involvement of several high-ranking Russian officials in stealing massive tax payments from several companies, including the investment fund Hermitage Capital.

Magnitsky died in 2009 aged 37 after being held in a Russian jail for a year, where he was denied medical care.
