“None has got back to us to date,” said National Police Commissioner Pol General Chakthip Chaijinda.

He spoke up after Amnat Chotchai, director-general of the Office of Attorney-General’s International Affairs Department, went public about the fact that Thailand could not yet seek the extradition of Red Bull heir Vorayuth “Boss” Yoovidhya because police have not specified his address.

Vorayuth is accused of hitting a policeman with his Ferrari five years ago, dragging the victim’s body for several metres and failing to stop the car to help him. He fled Thailand earlier this year, just before his case went to the court.

“We are trying to locate him We have already asked about 190 countries, including Britain, whether Vorayuth is in their territory,” Chaktip said.
