The opened case concerns the "possible illegal transportation of persons across the state border," prosecutors said, as quoted by AFP.
In October, Lithuania refused to probe accusations that Mustafa Hawsawi was imprisoned on its territory at one of the secret US Central Intelligence Agency (CIA) jails – known as "black sites" – between 2004 and 2006.
Prosecutors in Vilnius said that human rights groups which brought up Hawsawi's case had failed to provide any evidence of wrongdoing and that a previous investigation had ruled out claims that Al-Qaeda suspects were brought to the Baltic country.
But a high court ruled in January that prosecutors should ask authorities in the US for testimony from Hawsawi before making a final decision on whether to continue the case.
Human rights activists hailed the Thursday decision, saying that it could set an example for other countries facing allegations of hosting secret CIA jails – such as Bulgaria, the Czech Republic, Poland, and Romania.
"We certainly hope that it will serve as an example for other countries. And we trust that the investigation will be carried out to get to the bottom of these allegations," Sarah Fulton, a lawyer at Redress human rights organization, told AFP.
Rights groups behind Hawsawi's case claim their evidence is based on flight data, transfers of other suspects, and information about alleged CIA secret prisons in other countries.
Hawsawi is the second terror suspect to say that he was illegally held in Lithuania. Abu Zubaydah, an Al-Qaeda operative who is being held indefinitely at Guantanamo, has made the same claim.
