Ukraine’s former justice and energy minister was charged Monday in connection with a sweeping money laundering scheme, months after he resigned from office over the scandal. 

German Galushchenko was “exposed for money laundering and participation in a criminal organization,” according to the country’s two leading anti-corruption agencies, the National Anti-Corruption Bureau of Ukraine and the Specialized Anti-Corruption Prosecutor’s Office. The charges came a day after Galushchenko was arrested trying to leave the country. They revolve around a kickback scheme in the country’s public energy sector, involving Energoatom, a state-owned nuclear power company.
