On this day, Sept. 28, in 1975, three armed men set off to rob the Spaghetti House restaurant in Knightsbridge, London, kicking off what would become a six-day siege.

Nine staff members were at the Knightsbridge restaurant that evening collecting the weeks’ £13,000 of revenue when the gunmen, lead by Nigerian Franklin Davies, forced them into a storage room where they were held hostage.
