This week, ICE agents across the U.S. arrested or charged some of the worst criminal aliens hiding in plain sight.
From war crimes to violent sexual assaults, these foreign nationals entered or remained in the country illegally—and endangered the communities around them. Here are five among the worst of the worst detained this past week.
Vincent Nzigiyimfura – Genocide ringleader in Ohio
ICE Homeland Security Investigations (HSI) Detroit arrested 65-year-old Rwandan national Vincent Nzigiyimfura, pictured above, in Ohio. He’s accused of hiding his role in the 1994 Rwandan genocide, where he allegedly led coordinated attacks that left hundreds of Tutsi civilians dead. Convicted of genocide in absentia by a Rwandan court, he was indicted in the U.S. for immigration and naturalization fraud.
“No one wants a war criminal as their neighbor,” said HSI Detroit’s Angie Salazar. “We will never stop pursuing those who think they can hide from justice in our communities.”
