Nivell Rayda & Zaky Pawas, Jakarta – Disappointed by the National Police's "half-hearted" investigation, Indonesia Corruption Watch on Monday said it would lobby the House of Representatives to start its own probe into suspicious bank accounts allegedly belonging to senior officers.

"The National Police has investigated the accounts half-heartedly. We cannot even say that police have investigated the accounts because all they did was simply issue statements to clarify allegations against those officers in question," ICW deputy chairman Emerson Yuntho said.

The National Police announced on Friday that only two of 23 reports it had received from the Financial Transaction Reports and Analysis Center (PPATK) linking police officers to shady financial transactions pointed to criminal activity.

The two were identified as Comr. Martin Reno, an officer with the Papua Police who has already been tried in relation to his suspicious account, and embattled Comr. Gen. Susno Duadji, who is currently detained on graft charges for allegedly taking a Rp 500 million ($55,000) bribe from a suspected case broker.

Denny Indrayana, secretary of the presidentially appointed Judicial Mafia Eradication Task Force said that the team would evaluate police findings.

"The task force respects the internal process at the National Police [in investigating the accounts]. On the other hand the task force notes that civilian societies have reacted strongly against those findings," Denny said.

Separately, South Jakarta Police on Monday questioned ICW researcher Tama Satrya Langkun, who was ambushed on July 8 by four assailants and was hospitalized with multiple injuries.

There has been speculation the assault was connected to Tama's reporting to the Corruption Eradication Commission (KPK) and the task force that a number of police generals had suspiciously large bank balances.

But Tama said he was only questioned about his activities prior to the attack. "I was quizzed for six hours but none of the questions were related to my attack on Thursday morning," he said. "Investigators said they would summon me again on Wednesday."

Three days before the beating, Tama told the Globe that he was being stalked by four unidentified men. Several ICW activists noted that there was a black Toyota Innova parked near the group's office in the Kalibata area of South Jakarta.

But Jakarta Police spokesman Sr. Comr. Boy Rafli Amar said police were having difficulty identifying Tama's attackers. The police sketches of the attackers were "not perfect because after all, those attackers were wearing helmets," he said.

But he added that police were investigating the case thoroughly and there was more than one way to identify the assailants.

The National Police last week promised to arrest Tama's attackers within the week but acknowledged on Friday that they had failed to do so.

Usman Hamid, a coordinator from the Commission for Missing Persons and Victims of Violence (Kontras) said that he was disappointed as the National Police failed to meet its own deadline of arresting the attackers.

"The police did not fulfill their promise to capture the perpetrators. They also failed to show sincerity to fully investigate suspicious accounts which allegedly involve police officers," Usman said.
