"Based on the test results made by Russian doctors, Ukrainian professor Vasyl Prytula, Pavlo's doctor since childhood, has made a medical conclusion regarding the progression of Pavlo's disease. Pavlo has new diseases such as the initial stage of cirrhosis of the liver. When he [Pavlo] was examined by a neuropathologist yesterday, the doctor said he had symptoms of Alzheimer's. My wife said the doctor was shocked by his state of health," Pavlo's father, Ihor Hryb, told the Current Time TV channel.

Ihor Hryb reiterated Pavlo was being prepared for surgery in 2017 before he was abducted.

"He has been behind bars for more than a year and a half. Where he was beaten, where he was bullied, suffering from constant psychological pressure, inhuman conditions. And I want to remind everyone that he has been disabled since childhood. If surgery is not urgently done, he will die," Ihor Hryb said.

As UNIAN reported earlier, in August 2017, Pavlo Hryb was abducted from Belarus by the Russian FSB security force and consequently illegally arrested in the Russian Federation. Trumped-up charges have been pressed against the young man under Article 205 of the Criminal Code of the Russian Federation (an act of terrorism). Russian investigators accused Hryb of allegedly plotting a terrorist attack at a school assembly in Sochi.

Pavlo Hryb is diagnosed with portal hypertension, which requires daily intake of necessary medications and a special diet, the lack of which could become fatal. Russian authorities do not allow access of Ukrainian doctors to examine the political prisoner's health.

On July 23, 2018, the court in Rostov-on-Don, Russia, returned the indictment against Hryb to prosecutors and extended his arrest until October 22, 2018.

On October 25, Krasnodar Krai's prosecutors sent back the Hryb case to the North Caucasian district military court.
