After the U.K. request, Ukrainian prosecutors opened their own case, accusing Zlochevsky of embezzling public funds. Burisma and Zlochevsky have denied the allegations.
The case against Zlochevsky and his Burisma Holdings was assigned to Shokin, then a deputy prosecutor. But Shokin and others weren’t pursuing it, according to the internal reports from the Ukrainian prosecutor’s office reviewed by Bloomberg.
In a December 2014 letter, U.S. officials warned Ukrainian prosecutors of negative consequences for Ukraine over its failure to assist the U.K., which had seized Zlochevsky’s assets, according to the documents.
