Fifty-three years ago, convicted criminal Jan-Erik Olsson walked into a bank on Norrmalmstorg, a square in central Stockholm, pulled a submachine gun from under his jacket and fired at the ceiling. Concrete and glass rained down. “The party has just begun!” he shouted in a fake American accent, before taking four bank employees hostage.
Olsson demanded 3 million Swedish kronor, access to a getaway car, and the release of Clark Olofsson, a man he’d befriended in prison. The police met these demands, including supplying a full tank of petrol for the getaway car, but Olsson still refused to release the hostages or leave the bank.
