Rucha Krairerk, attorney general, said Vorayuth Yoovidhya, 28, faces three charges of reckless driving resulting in a fatal accident, failing to stop his car to help the victim, and driving at higher speed than permitted by the law.
Mr Vorayuth is an heir of the Yoovidhya family which owns the Red Bull energy drink business.
Vichien Klanprasert, a 47-year-old police officer at Thonglor station, was hit by Mr Varayuth’s Ferrari sports car which dragged his body more than 200 metres from the crash site on Sept 3 last year.
Mr Vorayuth’s lawyer, Thanit Buakiew, produced a medical certificate from a Singaporean hospital, dated Sept 1, addressed to the attorney general and said Mr Varayuth abruptly fell sick from influenza during a business trip in Singapore and could not return to Thailand.
Mr Rucha said he telephoned to Mr Vorayuth’s house several times yesterday but was unable to reach the lawyer.
The charge, valid for a year, expires today but the attorney general would file two more charges against Mr Vorayuth – reckless driving resulting in death, and failing to stop his car to help the officer who was hit by his car.
Mr Rucha said the attorney general's office would object to a bail request and would ask the police to issue an arrest warrant for for absent Mr Vorayuth.
