Stockholm syndrome is named after the Norrmalmstorg robbery of Kreditbanken at Norrmalmstorg in Stockholm, Sweden, in which several bank employees were held hostage in a bank vault from August 23 to August 28, 1973. During this situation, the victims became emotionally attached to their captors, rejected assistance from government officials at one point and even defended them after they were freed from their six-day ordeal. The term “Stockholm syndrome” was coined by the criminologist and psychiatrist Nils Bejerot, who assisted the police during the robbery and referred to the syndrome in a news broadcast. It was originally defined by psychiatrist Frank Ochberg to aid the management of hostage situations.
