The owners of the Royal Rose Private Hospital who went missing during an investigation into the hospital informed the police that they have been having a medical checkup in Singapore.
In a letter dated January 12, Tin Maung and his wife Nan Hla Sein said they were in Singapore and would return as soon as possible.
They have also submitted a letter of appeal related to the investigation into the hospital.
Police Lt-Col Sein Tun of Mandalay District said: "I've heard that they have submitted a letter of appeal stating that they have been offering the medical services of Chinese citizens at the hospital in accordance with the law. They have submitted it to various departments."
The police launched an investigation earlier this month into a clinic named Health News, on the third floor of the hospital, for providing medical treatment without a licence and distributing pornography. Six Chinese citizens and the hospital's owners went missing during the investigation.
The six Chinese fugitives left the country from Tada-U International Airport on January 4. The Myanmar police are requesting help from Interpol to track them down.
