United Nations Assistant Secretary-General, Bernt Carlsson, was the highest profile victim of the December 1988 Lockerbie bombing which killed all 259 passengers and crew on Pan Am Flight 103.

Whereas the Lockerbie trial that took place in 2000 assumed that the aircraft (a Boeing 747 jumbo jet) was the bombers' target and a Libyan man Abdelbaset al-Megrahi was wrongly convicted, no investigation has ever been carried out into the obvious targeting of Bernt Carlsson.

In May 2015, former Metropolitan Police Commissioner Sir Bernard Hogan-Howe failed (when requested by Lockerbie campaigner Patrick Haseldine) to undertake a Bernt Carlsson murder inquiry. Three years later, Hogan-Howe's successor Cressida Dick must take action to identify the real Lockerbie bombers.
