Rwanda has welcomed the arrest of Fulgence Kayishema, one of the fugitives most wanted for crimes they committed during the 1994 Genocide against the Tutsi. Kayishema, who has been on the run for more than 20 years, was arrested in South Africa on Wednesday, May, 24, in a joint operation by the International Residual Mechanism for Criminal Tribunals (IRMCT) and South African authorities.

In 1994, Kayishema was the head of the judicial police in the former Kibuye prefecture. Kayishema is alleged to have orchestrated the killing of approximately 2000 Tutsi refugees – women, men, children and elderly – at the Nyange Catholic Church during the 1994 Genocide against the Tutsi in Rwanda. In 2012, the UN tribunal ruled that upon his arrest, Kayishema would be transferred to Rwanda for trial.

For more than 20 years, Kayishema relied upon a network of trusted supporters, including family members, members of the former Rwandan army and FDLR, and those aligned with the genocidal Hutu Power ideology, the IRMCT said. Kayishema was located and arrested through an analysis-driven investigation exploiting multi-source evidence with both traditional and leading-edge methodologies.
