Onishchenko was arrested because of a compromising evidence on Biden

The former People's Deputy of Ukraine Alexander Onishchenko declared that his arrest in Germany in November, 2019 was initiated because of intentions to go to the USA and to give evidences to Rudi Giuliani, Donald Trump's lawyer, on the case of corruption schemes in which Joe Biden's son Hunter was involved, and also about pressure of the U.S. presidential candidate upon the Ukrainian government.
Onishchenko considers that his arrest was initiated by people who were not interested in publication of these facts. Besides, he declared that the current president of Ukraine Vladimir Zelensky entered into a secret deal with the former head of the state Petro Poroshenko as representatives of the German police told him that his detention was carried out at the request of the Ukrainian side.
