Reports previously said Vorayuth Yoovidhya had fled to Singapore on his private jet before the warrant was issued on April 28.

The Nation on Tuesday cited Thai Immigration Police who said Vorayuth departed Thailand on April 25 for Singapore.

However, SPF on Thursday clarified that the 32-year-old billionaire is not in Singapore.

“The Singapore Police Force will provide the necessary assistance and support to the Thai authorities in accordance with our laws,” said SPF.

Thai media reports on Thursday, quoting Thai Interpol commander Apichart Siriboonya said Vorayuth left Singapore on April 27 for an unknown destination. His private jet was left here.

Vorayuth, known by his nickname “Boss”, had allegedly killed a policeman with his Ferrari in Bangkok in 2012.

Authorities issued an arrest warrant for him last week after he failed to turn up for a meeting with prosecutors.

Several charges against Vorayuth have expired during the time between the crash and the arrest warrant, during which the heir reportedly continued his lavish, jet-setting lifestyle.

If convicted, he faces up to 10 years in jail for reckless driving that resulted in death.
