According to Lithuania's LNK TV, sources have told investigators that state security was involved in coordinating the construction of the prison, and have also provided the code name of the operation to transport terror detainees to the prison.
Arydas Anusauskas, head of the parliamentary committee investigating the prison, told ABC News he would not comment on the investigation until it is completed. He has previously said the results of the probe will be made public Dec. 22.
On Nov. 18, ABC News revealed the location of a secret prison, where harsh interrogation techniques were allegedly used on accused al-Qaeda terrorists, in a converted horseback riding facility 20 kilometers northeast of the Lithuanian capital of Vilnius. Where affluent Lithuanians once rode show horses and sipped coffee at an attached café, the CIA installed a hidden concrete structure where it could hold up to eight "high value detainees" at a time, a current Lithuanian government official and a former CIA official told ABC News.
For many of the residents of this former Soviet state, it is reminiscent of the KGB's secret prisons. "As a Lithuanian," a local woman told ABC News, "I am not very proud of this."
"The activities in that prison were illegal," said John Sifton, a New York attorney whose firm One World Research investigates human rights abuses. "They included various forms of torture, including sleep deprivation, forced standing, painful stress positions."
After ABC News revealed the location of the prison, a top Lithuanian official said that the report was damaging to his country's reputation.
"Obviously, this is not helping Lithuania's image," Foreign Minister Vygaudas Usackas told the Baltic News Service. "Therefore it is vital that we conduct an investigation and clear any doubts." Usackas also warned Lithuanians not to believe "rumors or wild tales."
It is not known which suspected al-Qaeda figures were in Lithuania, but 9/11 mastermind Khalid Sheikh Muhammad was moved out of the CIA's secret prison in Poland just before the Lithuanian facility was opened. According to sources who say they saw the facility, the riding academy originally consisted of an indoor riding area with a red metallic roof, a stable and a cafe. The CIA built a thick concrete wall inside the riding area. Behind the wall, it built what one Lithuanian source called a "building within a building."
On a series of thick concrete pads, it installed what a source called "prefabricated pods" to house prisoners, each separated from the other by five or six feet. Each pod included a shower, a bed and a toilet. Separate cells were constructed for interrogations. The CIA converted much of the rest of the building into garage space. Intelligence officers working at the prison were housed next door in the converted stable.
