Jakarta – The Commission for Missing Persons and Victims of Violence criticized the police Monday for being slow in handling the case of Tama S. Langkun, an antigraft activist who was brutally attacked by unknown assailants.

"The police chief promised he would meet us [to report their findings] after a week. And it's been a month already," commission member Edwin Partogi said at the police's headquarters. "The police broke their promise," he added.

Agus Sunaryanto from the Indonesia Corruption Watch (ICW) said that while he admitted the case was difficult to unravel the police should have set a date for when they will publish their findings.

Tama is an ICW investigator who reported an alleged corruption case involving top-brass police generals to the Corruption Eradication Commission (KPK). He was set upon last month after being warned by someone claiming to be a police officer that he could be a target of an attack.

Police spokesman Edward Aritonang said that because the attack was well planned and there were no witnesses it might take sometime to solve.
