South African authorities have opened an internal investigation into video footage allegedly showing police fatally shooting a suspected robber.
The CCTV video appears to show the suspect drop his pistol before he falls to the ground.
It then shows a policeman shooting him at close range.
In August eight policemen were convicted of murder after a bystander filmed them tying a taxi driver to the back of their van and driving away.
Both incidents happened near Johannesburg.
Police attention was brought to the most recent incident after South Africa’s Sunday Times newspaper published the footage.
According to the Sunday Times, the suspect attempted to rob a hardware shop in Krugerdorp, west of Johannesburg on October 19.
The newspaper says the police, acting on a tip-off, were waiting nearby and after the suspect left the shop he fired shots at the police van.
It quotes the spokesman for the Independent Police Investigative Directorate, Robbie Raburabu, as saying the post mortem showed shots to the head, chest and arm.
