On this day in conspiracies

Gibb airs a two-hour special, 'The Beatle Plot,' and the story becomes a national media event within days.

Thousands of Bishop's supporters march to his residence and free him, then move to Fort Rupert, the colonial-era fort above St George's harbour. Soldiers of the People's Revolutionary Army, loyal to the faction, storm the fort. Bishop and seven others are taken and executed by firing squad against a wall of the fort.

Machel attends a summit of Front Line leaders at Mbala, Zambia, alongside Kenneth Kaunda and Angola's Jose Eduardo dos Santos, focused on Zaire's Mobutu Sese Seko channeling support to the South African-backed UNITA. The Tupolev Tu-134A departs Mbala at about 18:38 for a non-stop return to Maputo.

On a Sunday morning at his home in Ikeja, Lagos, Giwa receives a parcel that his son brings to his study, where he sits with Newswatch's London bureau chief, Kayode Soyinka. Giwa reportedly remarks that it must be from the government, or 'the C-in-C,' just before the package explodes on his lap. He is gravely wounded and dies shortly after; it is Nigeria's first parcel-bomb killing.

In Georgensgmünd, Bavaria, a Reichsbürger adherent shoots four police officers during a raid to seize his weapons, killing one. The killing turns the movement from a bureaucratic nuisance into a recognized security threat; he is later sentenced to life.

About half an hour after the Louvre opens, a crew disguised as workers parks a truck-mounted basket lift against the Seine-side facade, cuts through a window into the Apollo Gallery, smashes two display cases with power tools and makes off with eight pieces of the French crown jewels, valued at roughly 88 million euros. The raid lasts only a few minutes; the thieves flee on scooters. This is the real, documented event.
