Jakarta – The National Police have been dragging their feet in investigating 20 major corruption cases, a watchdog says.

Indonesia Police Watch (IPW) chairman Neta S. Pane said investigations into the cases had been halted for five years. "[Police] should not neglect the cases," he was quoted as saying Sunday by news portal tempointeraktif.com.

Among the cases cited was embezzlement at state insurance company PT Jamsostek, in which former directors Horas Simatupang and Akmal Husein were declared suspects for stealing Rp 45 billion (US$5.28 million).

Another case revolves around doctored data at PT Darma Niaga that caused Rp 70 billion in losses to the state. Company directors Winarto, Wahyu Sarjono and Sudadi Martodirekso were declared suspects but there have been no further developments in the case.
