Inspector-general of police Khalid Abu Bakar has slammed Sarawak Report for "cooking up" a story to create suspicion among the community against the police.

He was referring to the latest allegation made by the whistleblower website that a key suspect in a graft investigation contacted Special Task Force for Anti-Vice, Gaming and Gangsterism (Stagg) chief Saiful Azly Kamaruddin 36 times in two months.

"The comments made by Sarawak Report (were meant to) deliberately create suspicion in the community," Khalid said at a press conference in Bukit Aman today.

Khalid dismissed a question posted to him on whether it was suspicious for K Gopinathan, the key suspect of "Ops Gopi" carried out by the Malaysian Anti-Corruption Commission (MACC), to have called Saiful frequently.

"A lot of people have called me every day, just to wish me 'good morning, sir', 'how are you today' and wishing me well. I (think I have received) hundreds of calls every morning. Is that suspicious? You can check my phone and make an analysis from it," he said.

"If you want to say that calls are something suspicious, well, I have commented about this and I don't want to entertain (anymore). Sarawak Report has made up a non-sensible story," he said.

Khalid added that he would give his fullest cooperation to the MACC if he is called for an interview.

"Sure. Why not?"

However, he said, the MACC has yet to contact him (on this matter).

"He said the MACC will call me for an interview if there is a need. It is up to him (to decide) as he is doing the investigation. I said that we will give the fullest cooperation to the MACC," he added.

Sarawak Report claimed that Gopinathan played a pivotal role in managing the police protection racket across gambling dens and prostitution houses in Malacca.

It claimed that Gopinathan contacted 20 senior police officers, including the top cop, and most of them are in the anti-vice squads.

As many as 12 suspects, most of them police officers, were arrested by the MACC in a swoop two months ago, codenamed "Ops Gopi".

Prior to this, Khalid admitted to knowing Gopinathan, but stressed that the latter would have to "answer for it" if he was involved in illegal activities.

Khalid also said the police would wrap up their investigation into 1MDB and resubmit the investigation paper as soon as the probe is completed.

However, he declined to give the reason the Attorney-General's Chambers (AGC) rejected the initial investigation paper.

"I am not going to reveal that. It is the subject of the investigation," he said.

The police formed an investigation team in April 2016 to scrutinise the Public Accounts Committee (PAC) report on 1MDB, a day after the PAC tabled the report.

The PAC report had, among others, stated that former 1MDB chief executive officer Shahrol Azral Hilmi should be held responsible for weaknesses in the investment firm's decision-making process.

The case is being investigated under Section 409 of the Penal Code for criminal breach of trust and Section 420 of the same code for fraud.

In April this year, Khalid told reporters that the investigation had been completed "some time ago".

On June 25, he said the AGC urged the police to dig deeper into the 1MDB issue.

The AGC and the police have been under increased pressure to wrap up investigations since the US Department of Justice's latest 1MDB-related civil forfeiture suits was filed on June 15.

Various opposition parties and civil society groups have criticised the Malaysian authorities for supposed inaction as their counterparts in Singapore, Switzerland, the US and other countries have cracked down on those implicated in the 1MDB scandal.
