When was the first time that you heard the term Stockholm syndrome?

It was this psychiatrist who is dead now, but he was a strange guy.

The term Stockholm syndrome was coined by psychiatrist Niels Beiro.

It became well known in 1974 when newspaper Eris Patti Hurst was kidnapped

by the Symbianese Liberation Army.

And instead of wanting to be rescued, she teamed up with the people who kidnapped her

and began to help them, rob banks.

But that's not where we get the term Stockholm syndrome.

One summer in 1973, two men robbed a bank in Stockholm.

They held four people hostage for six days.

The bank robbers had met one another in prison.

Their names were Jan Erich Olsen and Clark Olipsen.

Here's Clark.

The main thing was take it easy.

Nobody is going to get killed because I was the good guy.

And the police was the bad guy.

This is the beginning of the Stockholm syndrome.

By the time the two men met in prison, Clark had robbed a lot of banks.

He'd been to prison many times.

Clark became known all over Sweden when a robbery went wrong

and his friend shot and killed a policeman.

He'd become a kind of celebrity bank robber.
