Al Jazeera's "Rewind" section looks back at a 2013 investigation that revealed how the UK and American intelligence services cooperated with Qaddafi's regime to help detain, interrogate and torture Libyan dissidents.
The original 2013 piece tells of two Libyan dissidents abducted en-route to the UK, and repatriated to Qaddafi's Libya where they were imprisoned. They would only be released after Qaddafi's overthrow in 2011.
With the help of Al Jazeera, the two men investigated the events surrounding their abduction and found that they were captured by MI6 and forced onto CIA black flights to be taken back to Qaddafi's Libya, a controversial process known as rendition. The report also tells of previously unknown collaboration between British and Libyan intelligence services.
After the UK's involvement was revealed in 2013, both men received apologies and compensation from the British government.
Al Jazeera revisited the journalist who uncovered the story and obtained the Libyan documents detailing its cooperation the MI6. Although she refused to share her sources, she noted the level of closeness between the intelligence chiefs apparent from the documents.
