The woman at the centre of the so-called “nut rage” case in South Korea has been freed after nearly five months in jail.<br /><br /> Heather Cho, a former Korean Air Lines executive and daughter of the chairman, came to symbolise the arrogance of the rich and powerful.<br /><br /> Her furious on-board outburst at being served nuts in a bag not a dish sparked a thousand puns over how she roasted the crew and forced the plane back to the gate to expel its chief.<br /><br /> An appeals court suspended Cho’s 10-month sentence, noting her lack of a previous criminal record and that she is the mother of young twins. <br /><br /> “I apologise on behalf of the defendant to all people who were hurt by this incident,” said her lawyer Yoon Seung-nam outside the court.<br /><br /> Judge Kim Sang-hwan said Cho, who resigned from her executive posts at the airline amid the scandal, said she would have had time to reflect on the mental anguish she had caused.
