A leading bank official has been fired after being exposed as a Nazi-themed dominatrix.

The 46-year-old had worked at the central bank of the Netherlands for eight years. However, for the past six of them, she has also been offering her sexual services at more than £300 an hour.

Identified only by her ‘professional’ name, Conchita van der Waal, she asked clients for requests, saying ‘the kinkier the better’.

Van der Waal’s website, which has been taken offline, shows a range of provocative images, including one of her wearing an SS cap.

She advises prospective clients: ‘I have a challenging career in international finance. It takes me to many places (mainly western Europe and America).

‘Business meetings, elegant suits, lace stockings, garter belts, hold-ups, stiletto heels. If only my colleagues, clients or boss knew that at night I enjoy my hobby of being a hooker.’

Her online advert advises that she is a native Dutch blonde who is a ‘high-class nymphomaniac and prostitute’.

She describes her greatest passion as ‘raunchy kinky sex with wild strangers and naughty men’. Quote, a Dutch magazine, reported that van der Waal had a ‘supervisory’ role at her country’s central bank while specialising in sadomasochism in her spare time.

After the magazine broke the story, the bank confirmed it had fired her over ‘integrity issues’.

Prostitution in Holland is legal although workers at the Dutch central bank are not allowed to engage in any activities which could bring the institution into disrepute, such as ‘indecent behaviour’.

It is claimed that van der Waal previously worked with ABN-AMRO, a state-owned bank based in Amsterdam.

She is also understood to have worked for Dutch bank ING, which was fined £417million in 2012 for violating US economic sanctions. It is not clear when she was employed by either institution. According to her website, van der Waal’s work outside the financial sector was far more exciting.

A picture from one of her online adverts shows the blonde sex worker sprawled across a zebra-print double bed. She wears a revealing leopard-print dress, surrounded by lit candles, champagne flutes and an ice bucket. The picture and the online advert vanished from the internet soon after her identity was exposed.

But the images were captured and reproduced by Quote magazine before they were taken down.

According to the Irish Times, van der Waal could face further action from Dutch authorities because she failed to register officially as a prostitute or abide by tax rules.

Sex workers in the Netherlands must ensure they have a VAT number and pay income tax, none of which the woman has reportedly done so far.

And she may also face difficulties because her ‘S&M studio’ is reportedly in a building where ‘immoral’ behaviour is specifically outlawed under the terms of the contract under which it was bought in 2012.

Following the revelations, the Dutch central bank said it would review screening procedures for new employees. It said that of the 5,469 prospective staff who had been screened since 2011, 614 had been rejected.
