PetroSaudi International (PSI) is hunting down several of its former employees, through the local authorities in the country, for leaking the company's email correspondence with 1MDB.
The Saudi Arabia-based company announced late yesterday that one of its former staff members was arrested in Thailand and the person is cooperating with the authorities on the matter.
"Xavier Justo ( photo ) was arrested at his home in Thailand by the Crime Suppression Division of the Royal Thai Police yesterday and charged with attempted blackmail and extortion against PetroSaudi International.
"Numerous computers, hard drives and other evidence were seized pursuant to a court-ordered search warrant and the investigation is ongoing," PSI said in a statement today.
Legal action being considered in other countries
It added that it was considering further legal action in other countries.
The action comes after whistleblower site Sarawak Report revealed several of the company's email communication with 1MDB.
The email have raised questions over the use of 1MDB's funds, some of which apparently went to Malaysian billionaire Jho Low ( photo ), with PSI as intermediary.
However, a PSI spokesperson said the issue has been "politicised" in Malaysia.
"We are relieved that Mr Justo will now face justice through the courts.
“We have been the victims of a regrettable crime that has unfortunately been politicised in Malaysia.
"We are happy to finally set the record straight and we apologise to the Malaysian people for the harm that one of our unscrupulous ex-employees has caused to them," the PSI spokesperson added.
