Kim Jong-un has executed a senior North Korean official by firing squad because he did not sit properly during a meeting.
Education minister Kim Yong-Jin, 63, was shot dead after his 'bad sitting posture' in parliament incurred the wrath of the North Korean dictator.
The slouching vice premier was interrogated and found to be an 'anti-revolutionary agitator' before his execution in July, a South Korean official said.
'Kim Yong-Jin was denounced for his bad sitting posture when he was sitting below the rostrum,' he added, referring to North Korea's parliament.
Kim Jong-un was in the government meeting and was infuriated after Kim Yong-Jin sat in his chair 'with a bad attitude'.
Another South Korean official said the education official's poor posture was spotted at a meeting on June 29, when Kim Jong-un was named chairman of a new national defence department.
'The trouble for Kim began after he was seen sitting with bad attitude during a meeting of the People's Supreme Assembly,' the official told South Korean newspaper JoongAng Daily.
'He was later accused of being anti-revolutionary following a probe and a firing squad execution was carried out in July,' he added.
