Airport security cameras captured his meltdown on soundless video and published it for the world to see, but now there's another video of the incident with sound.
In the new clip, Linkun is seen at the gate mid-tantrum, yelling, smashing the counter at the gate and picking up a metal sign and throwing it against a glass door.
Linkun, who is a member of a government advisory board in Yunnan province, later apologized for his misbehavior in a statement through the Shanghai Daily.
"I failed to be a qualified political adviser, as well as a good father," Linkun said.
As of last Wednesday police were still investigating the case, and though Linkun had not been charged with anything he was suspended from his job.
