Ali al-Megrahi, the son of the late Abdelbaset al-Megrahi, lost his appeal against his father’s conviction for the 1988 atrocity.
According to the Times, the 53-year-old was found dead on 15 August after he was allegedly attacked by the former husband of the woman he was living with in the Bulgarian capital of Sofia.
The Scottish Criminal Cases Review Commission (SCCRC) referred the case to the High Court in March, ruling a possible miscarriage of justice may have occurred.
