A subsidiary of Japanese gaming conglomerate Universal Entertainment Corp. has asked the Philippine Department of Justice (DOJ) to punish the prosecutor who leaked the twin rulings on the $10 million perjury and fraud cases of billionaire Kazuo Okada.

Tiger Resorts Leisure & Entertainment Inc. (TRLEI) also appealed to Philippine Justice Secretary Menardo Guevarra on Monday to take over the leakage probe from Parañaque City Prosecutor Amerhassan Paudac, according to a Manila Standard report.

Paudac had already called for an investigation on the incident last week but TRLEI feared that a self-serving probe would only result in a whitewash. TRLEI described the Paudac-led probe as “improper, self-serving and unjustified.”

“It is the DOJ, not the panel formed by Paudac that should properly investigate the leakage of resolutions that happened at the Paranaque prosecutor’s office,” TRLEI said, according to the news outlet.
