JOHANNESBURG (AP) — Video footage showing South African police fatally shooting a robbery suspect while he lies wounded on the ground has emerged. Authorities have opened an internal investigation.

The CCTV footage, posted on the website of South Africa's Sunday Times newspaper, shows the suspect being shot at close range and also kicked as he lies on a sidewalk last month in Krugersdorp, west of Johannesburg.

South African media say the suspect, identified as Khulekani Mpanza, had earlier fired on police. In the video, Mpanza appears to drop a pistol as he falls to the ground after being shot the first time.

The African News Agency quotes police Lt. Gen. Lesetja Mothiba as saying any police officers who acted unlawfully will be prosecuted.
