( CNN ) -- A former prison guard responsible for leaking videos purportedly showing the abuse of prisoners at a penitentiary in the former Soviet republic of Georgia said Friday that he witnessed such torture on a daily basis since 2005 . `` While working in prison , I used to witness beating of prisoners , torture of prisoners , humiliation of prisoners on an everyday basis , '' Vladimir Bedukadze told CNN . The acts were recorded in four videos that were made public this week and show prisoners being physically and sexually assaulted , humiliated and verbally abused by prison officers . Purported prison abuse videos prompt outrage in Georgia . Bedukadze left the country three months ago and is now seeking political asylum in Belgium in the wake of the tapes ' release . Georgia television stations , including TV9 , broadcast the videos Tuesday night . The faces of those being filmed were obscured . One man cries out while he is being raped with a broom handle . Another video shows an inmate being punched . Bedukadze slammed the administration of President Mikheil Saakashvili , accusing the leader of allowing a `` campaign of torture , humiliation '' under former Interior Minister Bacho Akhalaia . `` I have been working in the system since 2001 , but since 2005 when Akhalaia was put in charge , he introduced his criminal elements of leadership , '' Bedukadze said . Akhalaia resigned his post Thursday after the videos ' release prompted outrage both inside and outside the Eurasian country . Georgia 's minister of corrections and legal assistance has also stepped down . And Saaskashvili himself condemned the abuse , saying Wednesday that what occurred at Gldani No . 8 penitentiary in Tbilisi is `` a horrific affront to human rights and human dignity . '' Bedukadze said he had been collecting the footage for more than a year . `` When I realized that I could not take it any more , I decided to reveal it and depart for Europe , '' he said , calling for Saakashvili to resign and accusing the president of establishing `` a criminal government with the leadership of Akhalaia . '' His comments echo a key allegation made by Georgia 's opposition , which says senior government officials sanctioned the abuse . Saakashvili has said an active investigation is under way into those responsible , with some arrests already taking place . The country 's interior ministry on Tuesday blamed certain prison employees for the degrading treatment . The ministry said a prisoner at the facility offered `` substantial reimbursement '' to employees for their actions and the video recordings . Its statement did not elaborate on the prisoner 's motivation . The interior ministry identified that prisoner as Tamaz Tamazashvili , father-in-law of Irlakli Garibashvili , a member of the opposition Georgian Dream party . Garibashvili said Tamazashvili 's life was in danger and that he was being held `` hostage '' by the president . Tamazashvili had nothing to do with the taped incidents , Garibashvili said . Bedukadze insisted that he has no political motivations for releasing the videos , and said he is not affiliated with any political party . `` They made up a lie that I was paid by the opposition leader ... and meant to use it to benefit the opposition . This was not my goal . I left the country independently , '' he said . Meanwhile Friday , the United Nations added its voice to a chorus of condemnation over the abuse . The Office of the High Commissioner for Human Rights called on the Georgia government to ensure that these allegations are `` promptly , impartially and effectively investigated and that perpetrators are brought to justice , '' spokesman Rupert Colville said . `` We condemn the acts of torture and ill-treatment perpetrated against inmates at a prison and a juvenile detention facility in Georgia , '' Colville added . He said the victims must have access to medical and psychological support . Interim Interior Minister Eka Zghuladze said that the country has built strong state institutions over the years and that all torture will be eradicated . The country 's prisons were notoriously corrupt places where organized crime ruled , but those days are over , she said , citing personal experience . `` I allow myself to state this , as 18 years ago , I myself was the victim of police violence , and therefore , I am fully aware of my words and situation that we have in Georgia today , '' Zghuladze said . Torture is absolutely prohibited under human rights law , Colville said in Geneva , and Georgia has ratified the United Nations Convention Against Torture . He praised the condemnation of the videos by Georgia 's president and urged the government to stand by its promise to investigate all alleged human rights abuses , not just the ones exposed this week .
