"We have not yet confirmed the truth but the indications shown the task force are indeed true," he said after meeting with Attorney General Basrief Arief here on Friday.
It was earlier reported that former tax official Gayus Tambunan had left for Macau and Kuala Lumpur on September 24, 2010 while he was supposed to be in a police detention cell as a corruption suspect.
Gayus was earlier reported to have gone to Bali to watch an international tennis match in Bali.
Yunus said the indications that Gayus had secured his assets abroad were strengthened by the finding of safe deposits in his name in Singapore.
"Together with the police we saw gold and cash in one of the safe deposits," he said.
The safe deposits were in Singapore and therefore it was believed Gayus has gone abroad to secure his assets.
He said right now his office had applied for an investigation into the case in Singapore, Macau, Malaysia and Thailand through the Financial Intelligence Unit.
Earlier, the police had confirmed that the picture on the passport in the name of Sony Laksono resembled Gayus.
The National Police head of public relations Inspector General Anton Bachrul Alam said there was no doubt that the picture on Sony`s passport looked like Gayus.(*)
