KYIV (Reuters) -Ukrainian state security officials searched the home of billionaire businessman Ihor Kolomoiskiy on Wednesday, in what several media outlets said was an investigation into possible financial crimes. The Security Service of Ukraine (SBU) did not immediately reply to a request for comment about the reports, and Kolomoiskiy could not be reached for comment. A senior governing party official confirmed Kolomoiskiy's home had been searched - as well as that of a former interior minister - but did not state the reason for the search.
