Commander William Hucklesby, at the time head of Scotland Yard's anti-terror branch, reported that the detonated device was constructed using two pounds (910 g) of commercial or military grade explosives.

[1] A hospital spokesperson stated that all but five victims were released shortly after being treated for minor scrapes, cuts, and bruises.

[4] The bombing took place just three days after the murder of Yvonne Fletcher and wounding of 11 anti-Gaddafi demonstrators in the street by machine gun fire from the Libyan Embassy in London.

Libyan Arab Airlines used Terminal 2 for its flights into London Heathrow, which raised suspicion as to whether the two events were related.

John MacIntyre, a British customs official stationed in Terminal 2 when the detonation occurred, told The New York Times:[1] There was a bloody big flash, a bang, and lots of smoke.
