After three weeks of investigations, the Anti-Corruption Agency (ACA) is still tightlipped on details of its probe into the VK Lingam video clip.

ACA deputy director-general Abu Kassim Mohamed, when contacted today, refused to comment on several recent developments.

"We have to complete investigations first, then reveal the findings later," he said.

Abu Kassim said this when asked to confirm if the ACA had interviewed Lingam and tycoon Vincent Tan, as reported by several dailies last Saturday.

Tan's name was among more than a dozen mentioned allegedly by Lingam in a grainy eight-minute video released by PKR de facto leader Anwar Ibrahim on Sept 19.

Anwar had claimed that the video casts doubts on judicial independence and that elements of corruption had been exposed in the recorded footage.

Wait till tomorrow

Following this, party vice-president R Sivarasa lodged a report with the ACA on Sept 20.

Abu Kassim also refused to divulge what action would be taken against Sivarasa and Anwar's aide Sim Tze Tzin should they fail to reveal the source of the video by the deadline tomorrow.

"We'll just have to wait until tomorrow," said Abu Kassim.

The ACA has served a notice on Sivarasa and Sim to compel them to reveal the source of the video, failing which they could be jailed for two years. They have refused to comply to date.

Critics have slammed the ACA were turning the tables on PKR leaders by forcing them to reveal the source of the video, in the absence of a witness protection law.

Asked if the ACA had a timeframe to complete its probe, Abu Kassim said that investigations would be done as quickly as possible.
