FBI raided the offices of a company tied to Ukrainian oligarch Igor Kolomoisky.

According to the information on Cleveland.com

CLEVELAND, Ohio — The FBI on Tuesday raided the offices of a downtown Cleveland real estate company that owns several buildings in the city.

FBI agent Vicki Anderson said agents searched the offices of the Optima Management Group at One Cleveland Center. Optima is a conglomerate of companies across the United States that has interests in real estate in Cleveland, including One Cleveland Center and the 55 Building on Public Square. 

Anderson said agents also have served search warrants in Miami.

Authorities in Cleveland have been conducting a wide-ranging probe involving Ukrainian oligarch Igor Kolomoisky that has been ongoing for quite some time. Kolomoisky is a principal of the Privat Group, a large Ukrainian business company, and principals of the company are also part of Optima.

Optima had a much larger presence in Cleveland about a decade ago when it bought several buildings under the leadership of executive Chaim Schochet. Its presence in Northeast Ohio has dwindled in recent years.
