Rwamucyo,63, previously served as a doctor at the Maubeuge Hospital (northern France).
The development follows the decision of the Court of Cassation in France which rejected the request to cancel his trial.
Rwamucyo is accused of being at the helm of masterminds that planed the genocide in former Butare prefecture.
On 2nd September 2009, Rwamucyo was handed life sentence in absentia by Ngoma traditional Gacaca court after he was found guilty of creating groups that mobilized the execution of the Genocide, providing weapons for the purpose of killing, capturing female Tutsis and registering the number of deaths.
Upon arrival in France, Rwamucyo secured a job at the University Hospital of Lille and was later hired by Maubeuge Hospital. He was suspended in October 2009 and when the establishment’s management learned that he was the subject of an international arrest warrant issued by Kigali, he was fired.
Rwamucyo was arrested on 26th May 2010 by Interpol based on the arrest warrant issued against him by Rwanda’s Prosecution.
He was arrested at Sannois graveyard while attending the burial of Jean Bosco Barayagwiza who had died in the United Nations detention facility in Benin.
Rwamucyo was taken into custody for four months and released on 15th September 2010. At the time, Versailles Court of Appeal rejected his deportation to Rwanda but ruled that he had to face justice in France being out of jail.
