In 2007, Johann Lamont, then deputy minister for justice, introduced an amendment that makes it easier for Scottish ministers to return a prisoner released on compassionate grounds to custody if they believe the grounds for release are no longer justified.
It is thought the Megrahi may have fled his home as the Gaddafi regime crumbled. Scottish authorities said several days ago that they had lost contact with Megrahi during the

Mohammed al-Alagi said the National Transitional Council was not prepared to hand him over. It was Gaddafi who handed over Libyan citizens," he said, referring to the ousted dictator's decision to turn Megrahi over to a Scottish court for trial.

Lockerbie bomber Abdelbaset al-Megrahi has left Tripoli amidst the ongoing civil war in Libya, probably evacuated by Libyan dictator Muammar Gaddafi, just as the UK government said he might be wanted again.
The former Lybian intelligence officer, Abdelbaset Ali Mohmed Al Megrahi, sentenced as the perpetrator of the 1988 Lockerbie Bombing, has thus captured again global media attention two years after he was released from a Scottish prison on August 20, 2009.

Ultimately, convicted bomber Abdelbeset Ali Mohmed al Megrahi was released on compassionate grounds because he is dying of cancer, a decision that Scottish, British and Libyan officials have said was not linked to oil or trade. Al Megrahi has terminal prostate cancer.
