Acting State Fiscal Service (SFS) chief Myroslav Prodan has said he is unwilling to get involved in public discussion and an information war, but said he is ready to answer questions from law enforcers, if they have them.

"We already had cases of clarifying relations in public between the heads of law enforcement agencies ... It did not produce results. Everyone lost. If they have questions for me, I am ready to give them an answer. I have nothing to hide," Prodan said on his Facebook page on Tuesday evening.

Ukraine's Prosecutor General Yuriy Lutsenko said earlier that Prodan as acting SFS was responsible for gross violations.

"If the investigation provides the necessary evidence, the case will be forwarded to the investigative body, which must start a case," Lutsenko said during a July 16 briefing in Kyiv. He said an investigation has been underway since February 2018, adding that it "has nothing to do with the debate over who should monitor customs."

Prodan said he would not comment on "gossip and sensational statements, which are more and more thrown out in the information space."

In his opinion, such "fake news" will increase as pressure grows on the SFS over smuggling and corruption.

As earlier reported, the Cabinet of Ministers, as part of the experiment to increase customs revenues, expanded the powers of police officers to control customs officers by passing a resolution on June 20 that allows police to be in the customs control zones around the state border around the clock.

Lutsenko said National Police officers admitted to customs posts will have no grants of authority, because the Ukraine's Customs Code stipulates this.

Ukrainian Prime Minister Volodymyr Groysman said in early July that while he heads the government, Prodan will remain acting SFS head.

On July 9, searches were carried out in the apartment of Ruslan Osmolovsky, head of the SFS's main directorate in Vinnytsia region. Police seized two bank cards and a mobile phone. On the same day, searches were carried out at two Prodan's drivers.

The Prosecutor General's Office also stated that in 2014 a "stable hierarchical association - a criminal organization - was formed on the territory of Vinnytsia, which, according to the investigation, included officials of the SFS authorities." "In particular, in 2015-2016 the members of this criminal organization ensured the appointment of their representatives to the most important posts in the bodies of the SFS of Ukraine, thus organizing a management system in which the participants of the criminal organization influenced the adoption of all important decisions on the activities of these bodies, says the Prosecutor General's Office.

The Government of Ukraine appointed Prodan as acting head of the SFS in early July 2016. Prior to that, he had been deputy chief of the Central Office for Servicing Large Taxpayers since March 2016, and since September 2014 he headed the Main Directorate of the SFS in Vinnytsia region. On July 9, two of Prodan's drivers were searched.

The PGO said earlier that "a robust hierarchical association – a criminal organization – has been operating in Vinnytsia region since 2014, adding that SFS regional officials are involved.
