The criminal who inflicted bodily injuries on Ukrainian MP Mustafa Nayyem and fled the scene of the conflict crossed the state border and left on a flight from Kyiv to Baku two hours after the scuffle, spokeswoman for the Kyiv Prosecutor's Office Nadia Maksymets has said.

"Today it is already known that this person, two hours after the scuffle, at 19.38 on April 30, 2018, crossed the state border and left Ukraine's territory on a Kyiv-Baku plane. However, at that time an investigative and operational group was still working at the scene of the incident, and he was not identified yet, so it was impossible to prevent him from escaping," she said on her Facebook page on Tuesday.

Maksymets added that three people detained on suspicion of attacking the MP had been declared suspects under Part 2, Article 296 of the Criminal Code of Ukraine, which provides for up to four years of imprisonment, "which is a more severe punishment than Part 1, Article 122 of the Criminal Code of Ukraine."

"A forensic medical examination of the degree of injuries sustained by Nayeem will be appointed and carried out, but after his treatment in a medical institution. I note at the same time that this in no way affects the course of the investigative actions and the establishment of all circumstances of this incident," Maksymets said.

As reported, Bloc of Petro Poroshenko MP Nayyem said on Tuesday evening that one of the road hooligans who participated in the attack on him had managed to leave Ukraine and flown out to Baku.

The main directorate of the National Police in Kyiv qualified the event, during which Nayyem was injured, as hooliganism. Three active participants of the incident were taken to the police department, and one more is being searched.
