The Malaysian authorities are on the hunt for four North Korean male suspects aged 33 to 57 who fled immediately after the Feb 13 death of Mr Kim Jong Nam, the half-brother of North Korean leader Kim Jong Un.
At their first press conference on the alleged assassination, the Malaysian police said they are also seeking three other men - one of whom is North Korean - to help in the probe.
The post-mortem results will be ready in a few days, said Deputy Inspector-General of Police Noor Rashid Ibrahim.
He refused to comment on whether the attack was ordered by Pyongyang. But Seoul asserted yesterday that with five suspects being North Korean - including one who has already been arrested - it was clear Pyongyang was behind it.
Four people have been arrested so far, including North Korean IT worker Ri Jong Chol, who is based in Kuala Lumpur.
