Ukrainian oligarch Ihor Kolomoisky detained on suspicion of fraud and money laundering

Arrest of one-time ally of President Volodymyr Zelenskiy comes as Kyiv attempts to crack down on corruption

A Ukrainian court has ordered tycoon Ihor Kolomoisky to be held in custody for two months on suspicion of fraud and money laundering, a striking move against one of the country's most powerful businessmen.

The detention on Saturday of Kolomoisky, who is under US sanctions and is a one-time supporter of President Volodymyr Zelenskiy, whose election he backed in 2019, comes as Kyiv is trying to signal progress during a wartime crackdown on corruption.
