Red Bull

The untouchable Red Bull heir in Thailand

That Vorayuth Yoovidhaya, the grandson of the billionaire who invented the energy drink Red Bull, would once again fail to appear at a Bangkok prosecutor's office to face charges relating to the death of a police officer.

On 3 September 2012, that officer was struck by a Ferrari driven by Mr Vorayuth.

The sometimes farcical attempts by the Thai authorities to bring Mr Vorayuth to justice are now commonly cited as epitomising the untouchability of the super-rich in Thailand.

The facts of the incident early on the morning of 3 September are reasonably clear.
