ABC FINDS SECRET CIA TORTURE PRISON

ABC News - The CIA built one of its secret European prisons inside an exclusive riding academy outside Vilnius, Lithuania, a current Lithuanian government official and a former U.S. intelligence official told ABC News this week.

Where affluent Lithuanians once rode show horses and sipped coffee at a café, the CIA installed a concrete structure where it could use harsh tactics to interrogate up to eight suspected al-Qaeda terrorists at a time.

"The activities in that prison were illegal," said human rights researcher John Sifton. "They included various forms of torture, including sleep deprivation, forced standing, painful stress positions."
