"Few people know it, but back in 2014 Putin offered to release Dzhemilev's son and transfer him to the occupied Crimea in exchange for Mustafa Dzhemilev's loyalty, but the latter turned down [the offer]," she wrote.

Gerashchenko also emphasized that Ukrainian President Petro Poroshenko had raised the issue of release of Dzhemilev's son and his transfer to Ukraine in his communication with Putin.

As reported earlier, in 2013, Hayser Dzhemilev was found guilty of manslaughter with the use of his parent's gun of a family friend Fevzi Edemov.

After the annexation of Crimea, Russian investigative authorities decided to re-investigate. Hayser was taken from Simferopol jail to Krasnodar region of Russia.

The Supreme Court of the Russian Federation reduced his five-year imprisonment by year and a half.

However, Kyiv's Dniprovskiy District Court in April 2015 sentenced him to three years and eight months in prison. Hayser Dzhemilev was serving his sentence in Astrakhan colony No. 10.
