Metropolitan Police Bureau chief Pol Lt-General Sanit Mahathavorn said police had finished almost all the paperwork involved, such as translating the arrest warrant for Interpol to track Vorayuth down.

Vorayuth escaped an arrest warrant over the case in which he is accused of a hit-and-run collision in Bangkok that killed a police officer in 2012.

Sanit said that, according to the Immigration Bureau, Vorayuth came to Thailand on April 23 and left for Singapore two days later. It is still unclear whether or not he left the city-state.

However, following a meeting with the Foreign Affairs Ministry representative and Foreign Affairs Division Police, Sanit said that Vorayuth’s passport had been revoked, while Interpol would help Thai police arrest him if captured outside the country.
