Stockholm Syndrome is a situation in which people being held captive feel sympathy toward their captors and it all started right here at Nobis Hotel. The 'Norrmalmstorgdrama' went down over a period of six days, from August 23 through August 28, 1973. On the first day, Jan-Erik Olsson strolled into Kreditbanken, now Nobis Hotel, in central Stockholm, and single-handedly held the place up. Of the two policemen who responded to the call, Olsson shot one in the hand and made the other sit in a chair, ordering him to sing something. Olsson then took four hostages and started making demands: He wanted his friend and expert bank robber Clark Olofsson brought to the bank. He wanted 3 million Swedish Kronor. And he wanted a couple of guns, some bulletproof vests, some helmets, and a fast car.
On August 28, 5 days of drama, police finally decided to gas everyone out via a hole they had drilled through the ceiling of the bank vault. The ploy worked, and everyone eventually left the bank unharmed. Both Olofsson and Olsson were captured. Today the drilled holes are filled but you can clearly see them when walking in the corridors at Nobis Hotel.
