In the course of the investigation on 13 March 2017 the prosecutor of the Branch Commission for the Prosecution of Crimes against the Polish Nation of the Institute of National Remembrance in Lublin asked the District Court Lublin-West - Third Criminal Division to issue an arrest warrant for Michael K.

On 14 March the Lublin District Court accepted the Prosecutor's request and ordered provisional detention for a period of three months from the date of the arrest. The court's decision opens the way for an application to be sent to the US authorities for the extradition of Michael K. to Poland.

Michael K. is suspected of committing crimes against humanity, constituting at the same time a war crime. On 23 of July1944, as a company commander of the German-led Ukrainian Self Defence Legion, he commanded his subordinate soldiers to kill rural residents of  Chłaniów, Kolonia Chłaniów and KoloniaWładysławin and burn down the buildings in those villages.

Soldiers of the Ukrainian Self Defence Legion pacified the above villages killing 44 inhabitants and burning down residential and farm buildings.

The findings in the course of the investigation indicate that Michael K. is an American citizen residing in the US. For this reason, the prosecutor of the Branch Commission for the Prosecution of Crimes against the Polish Nation of the IPN in Lublin intends to apply to the American administration to seek the extradition of the suspect residing in the US to Poland.
