This was reported by TASS with reference to Poroshenko's lawyer Igor Golovan.
According to him, the former Ukrainian leader was not allowed to go abroad without any grounds, as a result of which a statement about a criminal offense was sent to the Prosecutor General's office.
"It didn't give any result, which shows blatant inaction," Golovan said.
Earlier, the SBU recommended that the Rada not allow Poroshenko to leave Ukraine for a meeting with Hungarian Prime Minister Viktor Orban.
Later, Poroshenko criticized the situation in the Armed Forces of Ukraine and at the front during a speech in the Rada.
