According to the parliamentarian, the SBU officers summoned him for questioning by a summons, the photo of which is attached to the post in the social network.
The reason for the investigation, according to the deputy, was that in August 2017 Poroshenko allegedly donated 100 sniper complexes to a regiment of Ukrainian special forces for the amount of 500 million hryvnia (about 1.2 billion rubles).
"In order to clarify the legality of such an operation and the mechanism for transferring weapons to the APU, I sent a request to the Ministry of Defense," Kupriy wrote on his Facebook page.
According to the politician, the head of the department Stepan Poltorak informed him that, according to the agreement on the purchase of goods for charitable purposes, not 100, but 98 units of hunting weapons were transferred to the servicemen.
At the same time, Poltorak stressed that disclosure of this information to the media could damage the interests of the state.
"Thus, on the initiative of Petro Poroshenko and for the purpose of dissemination in the media, a demonstration of weapons was sent to our military, which, according to Stepan Poltorak, could harm the interests of Ukraine's national security and is a military secret," concluded Kupriy, suggesting that Poroshenko could "steal" the two missing rifles or hand them to his friends "as a gift."
In June, it was reported that law enforcement agencies of the British Virgin Islands began an investigation in connection with suspicions against Petro Poroshenko and mayor of Odessa Gennady Truhanov in money laundering.
Also, the General Prosecutor's Office of Ukraine opened a case against the Verkhovna Rada deputy Yevgeny Murayev on articles on state treason and deliberately false communication about the committed crime.
