'The suspects' identikits are expected to be released later in the afternoon'
Meyiwa was shot in his upper body in the Vosloorus, Ekurhuleni, while visiting his girlfriend, singer and actress Kelly Khumalo, on Sunday night.
One shot was fired inside the house and two more were fired randomly outside.
The attackers used a .38 revolver so no cartridges were left on the scene, police said on Monday.
The attackers demanded cellphones and money.
National police commissioner Riah Phiyega announced on Monday that she had set up a multi-disciplinary task team made up of forensic, crime intelligence, and visible policing members to handle the case.
A reward of up R250 000 was being offered for information that could lead to the arrest and conviction of the killers.
Malila said information on the identity of the alleged killers was being corroborated for identikits.
"The suspects' identikits are expected to be released later in the afternoon," he said.
