Prosecutors in Scotland are reportedly investigating retired Stasi agents over the Lockerbie bombing.

The Times Scotland says officials from the Crown Office are examining the possible role of the East German intelligence service in the 1988 bombing and former agents have been questioned in Germany at their request.

The bombing of Pan Am flight 103, travelling from London to New York four days before Christmas, killed 259 people on board.

Eleven residents of the Dumfries and Galloway town also died after the plane crashed into their homes in Britain’s biggest terrorist atrocity.

Former Libyan intelligence officer Abdelbaset al-Megrahi, the only person ever convicted of the bombing, died in 2012 after being released from prison early on compassionate grounds.

Investigators do not believe Megrahi acted alone but others, including relatives of some of the victims, believe he was wrongly convicted and his family are seeking legal permission for a fresh appeal against his conviction.

A Crown Office spokesman said: “Prosecutors and police, working with UK Government and US colleagues, will continue to pursue this investigation, with the sole aim of bringing those who acted along with Al Megrahi to justice.

“As this is a live criminal investigation, it would not be appropriate to comment.”
