How were the alleged wrongdoings revealed?

This week WikiLeaks published more than over 30,000 documents (the first of two batches) it said it obtained from a whistleblower within Samherji.

James Hatuikulipi, the managing director of South Africa-based Investec Asset Management, has resigned effective immediately amid the corruption probe related to allegations involving Icelandic fisheries giant Samherji.

His right hand man and Client Director Ricardo Gustavo was also forced to temporarily step down as internal investigations take place.
