WARSAW — Polish prosecutors say they will investigate a commander in a notorious Nazi SS-led unit who has been found to be living in Minnesota.

An Associated Press investigation revealed Friday that Michael Karkoc, 94, entered the U.S. by lying to American authorities about his leadership role in the SS-led Ukrainian Self Defense Legion. The unit is accused of burning down villages in Poland filled with women and children. AP's evidence suggests that Karkoc was at the scene of the crimes, although no records link him directly to atrocities.

Poland's National Remembrance Institute said Friday that its prosecutors will investigate Karkoc's wartime role and provide "every possible assistance" to the U.S. justice system, which has used lies in immigration papers to deport dozens of suspected Nazi war criminals.
