Rwandan officials have previously said that Mutabazi, a Rwandan army lieutenant who served on President Paul Kagame's security detail before defecting, was wanted back home over alleged robbery charges. He is accused of robbing a bank in the Rwandan capital, Kigali, more than two years ago.
Many journalists and former civilian and military officials have fled Rwanda, alleging persecution. In the most prominent case, Gen. Faustin Kayumba Nyamwasa, a Rwandan army chief who once was a close Kagame ally, defected to South Africa in 2010 and later accused Rwanda's government of ordering a failed attempt to assassinate him. Rwanda denied the allegations.
Mutabazi, who had lived as a refugee in Uganda since 2011, "survived a bungled abduction" in August as well as an assassination attempt in July 2012 in Uganda, in both cases by unknown perpetrators, according to Human Rights Watch.
