Libyan Prime Minister Ali Zeidan has accused a "political party" with his seizure on Thursday, without identifying the name of the group Al Arabiya reproted.
Saying that he had been taken hostage, the prime minister stressed that his abductors "want only to overthrow the government, by force, by democracy, by non-democratic means, or by any means whatsoever".
"It's a political party which wants to overthrow the government by any means," he said in an interview with the France24 television channel, carried by Agence France-Presse.
Zeidan has been briefly abducted by former Libyan rebels, who seized him from a hotel earlier on the day, and held him for several hours.
The premier appeared in good health when he arrived at government headquarters after his ordeal, waving to waiting well-wishers as he climbed out of an armored car.
He appeared live on television during a cabinet meeting where he thanked some rebels who helped his release, according to Reuters.
The brief abduction of Zeidan came five days after U.S. commandos embarrassed and angered the government by capturing senior Al-Qaeda suspect Abu Anas al-Libi on the streets of Tripoli, whisking him away to a warship in the Mediterranean.
Witnesses said Zeidan was held at a police station south of the capital, and that his captors released him after armed residents surrounded the building and demanded he be let go.
"In the coming days I will give more information on who this political party is that organized my kidnapping," Zeidan told France24.
The prime minister said that his hostage-takers had discussed the question of Abu Anas al-Libi.
He insisted that he had had no advance warning of the U.S. commando action.
