Thai police expect to receive a request from Taiwan authorities on Monday for help in tracking down a man suspected of murdering a Thai couple whose bodies were found last week in a parked car outside the Taoyuan high-speed rail station.
Pol Maj Gen Khemmarin Hassiri, commander of the Royal Thai Police's foreign affairs division, on Sunday said Taiwanese officials believe the culprit to be a Thai national who fled to Thailand shortly after committing the crime.
He said a letter is expected on Monday and that even though Thailand and Taiwan have no extradition treaty, police are ready to co-operate fully with any such request in relation to the murder of the couple whose bodies were found on Friday.
