He said in the video posted on Russian human rights resource Gulagu.net that authorities are trying to shut his mouth.
"It's a shame that instead of using the time to reform the system and investigate all this terrible evidence we gave them, they are trying to hide the truth," he added.
On October 6 Human rights activists published some videos showing the inmates being tortured by the jail guards and personnel. Over a thousand videos have been uploaded by Gulagu.net.
The video archive of shocking content was smuggled from the city of Saratov prison by Savelyev who served 7,5 years there for drug trafficking. He was asked to work as an IT specialist in prison and he managed to download the footage of tortures on a USB flash drive.
According to Gulagu.net founder Vladimir Osechkin: "it is the first time that human rights defenders have obtained such a colossal amount of information on abuses in Russian prisons.’’
Osechkin said that more than 200 inmates have been tortured and raped, with 40 depicted in videos.
