Businessman Dmytro Firtash is a witness in the case on bribing a representative of the criminal police in Germany, Deutsche Welle (DW) has reported, referring to the prosecutor's office in Schwerin.

"Currently Ukrainian billionaire Dmytro Firtash is not suspected… However, his status could be changed," DW wrote.

DW said that now a 69 year old woman from Berlin who under the guise of an employee of the consulting bureau sold information received for bribes from policemen and prosecutors is prime suspect.

"The woman is suspected of getting information for bribes from an officer of the criminal police of Mecklenburg-Vorpommern federal territory in the interests of Firtash. This officer obviously gave information on the course of investigation against him in the United States, where Firtash is accused of corruption," DW reported.

According to the article, the police officer sent inquiries to the United States, pretending to be an investigator in the Firtash's case.

"According to NDR TV, bribes for information for the Ukrainian billionaire could exceed EUR 500,000," DW said.

According to DW, on April 20, 2016 Firtash's house in Vienna was raided by the police. If new evidences appear in the case, the status of the businessman could be changed.
