Comr. Gen. Susno Duadji, the country's former most senior detective, is at it again, attacking National Police for what he alleges is their failure to protect him after he blew the whistle on alleged corruption involving senior officers.

Speaking to House of Representatives Commission III for law and legislation, Susno told the legislators on Thursday that instead of protection, "I received legal threats in the form of alleged defamation, for example."

Susno was referring to legal action launched by two senior officers from the National Police – Brig. Gen. Raja Erizman and Brig. Gen. Edmon Ilyas – who say he accused them of taking bribes in return for halting a probe into a Rp 25 billion ($2.75 million) corruption case involving allegedly corrupt tax official Gayus Tambunan.

He told the lawmakers that he had previously summoned Raja to his house in Depok to question him about the allegedly corrupt resolution of the Gayus case in the Tangerang District Court, including the police charges, but Raja did not give clear answers.

"Raja Erizman just laughed. He didn't answer my questions clearly, it seemed to me that somebody was pressuring him," Susno said.

In a document circulating among journalists, Raja asked the president director of PT Bank Panin to lift the freeze on Gayus' accounts because they had nothing to do with the criminal case and because prosecutors and police were investigating another account of Gayus's in a different bank.

In the letter classified as secret and dated Nov. 26, two days after Susno was dismissed as the chief of detectives, Raja told the Bank Panin director: "The evidence of the case is with another financial service provider, so the accounts... of Gayus Halomoan P Tambunan have no connection with the ongoing investigation. Accordingly, the assets in those accounts can be reopened."

Raja at that time served as the director for special economic crimes at Susno's former office. The letter, a copy of which was obtained by the Jakarta Globe, also referred to the prosecutor's recommendation in asking that the freeze on the accounts to be lifted.

Brig. Gen. Edmon Ilyas has officially been replaced as the chief of Lampung Police by National Police deputy spokesperson Brig. Gen. Sulistyo Ishak, while Raja is still yet to have any action taken against him despite also being implicated in the Gayus scandal.
