It is one of the oddest traits in human nature – when hostages start to side with their captors, defending their actions and even developing an affection for them.
Known as Stockholm Syndrome, it got its name from a bizarre bank robbery in the Swedish capital nearly 50 years ago, when a group held for six days grew close to the two men responsible and sympathised with them.
During the siege, one hostage even phoned Sweden’s Prime Minister from inside the bank to complain at his attitude to her captors.
