Immigration and Customs Enforcement spokesman Pat Riley said George Boley, of Clarkson, N.Y., was arrested Jan. 15 on charges that he is in the country illegally, and is also facing charges that he committed killings in another country, the Rochester (N.Y.) Democrat and Chronicle reported Sunday.
Boley's family has long contended that U.S. authorities have relentlessly pursued him even though allegations he committed atrocities during Liberia's bloody 1990s civil war are baseless, the newspaper said.
The Democrat and Chronicle said earlier immigration charges against Boley, 60, were dismissed when prosecutors failed to take the allegations to a grand jury quickly enough. Boley sued the federal government last year, alleging he was wrongly arrested, the newspaper said.
Liberia's Truth and Reconciliation Commission last year reportedly named Boley as one of eight people who should be prosecuted for alleged war crimes and human rights violations.
