Inspector-general of police Mohamad Fuzi Harun will look into claims made by Malaysian Anti-Corruption Commission (MACC) chief commissioner Mohd Shukri Abdull that he was stalked when he was in the United States during the height of the 1MDB investigation.

"I'm not aware of what happened as it was before my time but I'll look into this seriously," Fuzi is reported as saying by Channel News Asia.

At a tell-all press conference yesterday, Shukri, who during his probe into 1MDB in 2015 was MACC deputy commissioner, said his investigation caused him to be a victim of harassment, including being stalked while overseas and receiving bullets at home, by mail.

He said he was followed and photographed by individuals known to him while he was in Washington DC.

Shukri said he took photos of these individuals and passed the photos on to fellow MACC deputy commissioner Azam Baki to pass them on to then inspector-general of police Khalid Abu Bakar.

The MACC was investigating former prime minister Najib Abdul Razak on the transfer of RM42 million from SRC International into his private bank account.

A task force was set up in 2015 to probe the alleged mismanagement of 1MDB funds.

The task force comprised former attorney-general Abdul Gani Patail, former MACC chief Abu Kassim Mohamed, former Bank Negara Malaysia governor Zeti Akhtar Aziz and former inspector-general of police Khalid Abu Bakar.

Fuzi also said the police were trying to complete the 1MDB probe as soon as possible.

"Because the investigation is conducted not just by police but by many other parties. On our part we are trying to complete investigations as soon as possible," he said.

The police had in 2016 formed an investigation team into 1MDB to scrutinise the 1MDB report prepared by the Public Accounts Committee (PAC).

The police then were investigating 1MDB under Section 409 of the Penal Code for criminal breach of trust and Section 420 of the same code for fraud.
