The investigator, Ahmed Hussein-Suale, was notably exposed by Assin Central MP, Kennedy Agyapong in the aftermath of the #Number12 exposé on corruption in Ghana football.
He was reportedly killed by two gunmen on a motorbike who shot into the car he was driving.
Anas, in a message on Facebook said Ahmed was hit three times; twice in the chest and once in the neck following which he died on the spot.
This is the third of such an incident in which an individual has been shot and killed unknown assailants where nothing was taken from the deceased.
The most recent case was the killing of the Public Affairs Manager of the Tema Port, who was found stabbed and killed in her bedroom last Sunday.
In a war of words with the investigative journalist in July 2018, Mr. Agyapong went on a show on the TV station he owns, the Madina-based Net 2 TV, and urged residents to beat up Ahmed whenever they saw him.
Anas Aremeyaw Anas, in a video on his Facebook page, presented the announcement of his colleague’s murder within the context of Mr. Agyapong urging residents of Madina to go after Ahmed.
The journalist has also spoken to Graphic Online about the incident.
“He was just shot and killed, nothing was taken from him”, another member of the Anas’ team told Graphic Online.
The police is however yet to comment on the matter, although his remains have been deposited at the Police Hospital.
Mr. Agyapong has been criticised for inciting violence against Anas and his team.
The MP accused the investigator of being corrupt and evil in the wake of his probe into Ghana football.
He also said Anas deserved to be hanged for his purported corrupt deeds.
Reporters Without Borders came out to say it was alarmed by threats to the life of Anas.
The Ghana Journalists Association (GJA) at the time also called for 24-hour protection for Anas
