Current acting Deputy Inspector-General of Police Abdul Hamid Bador will most likely be the new police chief, Dr Mahathir Mohamad said today.

The prime minister, however, stopped short of confirming the matter, saying he "thinks" this will be the case.

"Yes, I think he is the next IGP.

"I think the Yang Di-Pertuan Agong has signed his appointment letter," he said when questioned by reporters after a Labour Day event in Putrajaya this morning.

Hamid was named as acting deputy IGP in March, replacing the retired Noor Rashid Ibrahim.

He led Bukit Aman's Special Branch before being removed from the police force by the Najib Abdul Razak administration in 2015.

Hamid was transferred to the Prime Minister's Department amid a clampdown on 1MDB investigations at the time.

However, he did not clock in at his new job, and went public 10 days later about his removal being linked to his insistence on probing the scandal surrounding the state investment firm.

Following Pakatan Harapan's win in last year's general election, Hamid was reappointed as the director of the Special Branch.

He will replace current IGP Mohamad Fuzi Harun, who retires on May 4.
