On 12 November 2019, WikiLeaks published thousands of Samherji emails and documents that indicated the Icelandic fishing company had paid hundreds of millions of Icelandic króna to senior Namibian politicians and officials to secure valuable fishing quotas. Former Samherji Namibia general manager Jóhannes Stefánsson, who was cooperating with anti-corruption authorities, told Icelandic broadcaster RÚV that CEO and major shareholder Þorsteinn Már Baldvinsson authorized the alleged bribes. The records also brought Norway’s Den Norske Bank under scrutiny for transferring money allegedly used in the scheme.
Samherji initially portrayed Stefánsson as the sole employee responsible, although the source says records showed he lacked control of the relevant Cyprus bank accounts and that payments allegedly continued for three years after his departure. Namibia’s fisheries minister Bernhard Esau and justice minister Sacky Shanghala resigned on 13 November 2019; Baldvinsson temporarily stepped aside as Samherji CEO on 14 November. By December, Esau, Shanghala, Tamson Hatuikulipi, James Hatuikulipi, Ricardo Gustavo, and Pius Mwatelulo—the “Fishrot Six”—had been arrested and accused of corruption, fraud, and tax evasion. The allegations remained subject to legal proceedings, while a 2020 anti-corruption investigation cited limited international cooperation and Stefánsson later reported fearing he had been poisoned.
