Ukrainian Authorities Arrest Prominent Oligarch in Anti-Corruption Crackdown

Ihor Kolomoisky, one of Ukraine's wealthiest oligarchs, was arrested on fraud and money laundering charges.
Kolomoisky's arrest signals Ukraine's efforts to combat corruption and reduce oligarchs' influence.
Ukraine aims to show Western allies that aid won't be misused and strengthen its EU integration case.
As Ukraine's 5th richest person, Kolomoisky held business interests in banking, oil and other sectors.
Laws preventing return of nationalized banks to former owners have limited Kolomoisky's power.
