An American jihadist who set up the terrorist training camp where the leader of the 2005 London suicide bombers learned how to manufacture explosives, has been quietly released after serving only four and a half years of a possible 70-year sentence, a Guardian investigation has learned.
The unreported sentencing of Mohammed Junaid Babar to "time served" because of what a New York judge described as "exceptional co-operation" that began even before his arrest has raised questions over whether Babar was a US informer at the time he was helping to train the ringleader of the 7 July tube and bus bombings.
Lawyers representing the families of victims and survivors of the attacks have compared the lenient treatment of Babar to the controversial release of the Lockerbie bomber, Abdelbaset al-Megrahi.
Babar was imprisoned in 2004 – although final sentencing was deferred – after pleading guilty in a New York court to five counts of terrorism. He set up the training camp in Pakistan where Mohammad Sidique Khan and several other British terrorists learned about bomb-making and how to use combat weapons.
Babar admitted to being a dangerous terrorist who consorted with some of the highest-ranking members of al-Qaida, providing senior members with money and equipment, running weapons, and planning two attempts to assassinate the former president of Pakistan, General Pervez Musharraf.
