The bigger the lie, the more it will be believed, to paraphrase the Nazi propagandist Joseph Goebbels. So when a South Korean man received an email promising him tens of millions of dollars in a lottery scheme if he travelled to South Africa, he fell for it.
The offer turned out to be a so-called 419 scam on an epic scale. South African police say the credulous man arrived with his daughter only for both to be taken hostage in a township for four days.
The kidnappers, a mainly Nigerian gang, demanded a ransom of $10m (£6.5m) but were thwarted by police who raided the house and freed the pair.
