Thailand’s Prime Minister ordered a panel be set up Wednesday to probe the dropped charges against the heir of the multi-billion dollar Red Bull franchise, who stood accused of a hit-and-run that killed a policeman eight years ago in Bangkok.

Prayuth Chan-ocha said in a statement he had ordered the fact-finding panel be convened to investigate why charges were dropped Friday against Vorayuth Yoovidhya, 28, who was accused of killing Sgt. Maj. Wichian Klanprasert with his Ferrari following a night out in 2012.EFE-EPA
