Eight police officers were arrested in South Africa March 1 after the death of a man they apparently tied to the back of a police van and dragged along a road in Daveyton, east of Johannesburg. Video footage showing the treatment of Mido Macia, a 27-year-old taxi driver and immigrant from Mozambique, went viral on the web, and was published by South African newspaper the Daily Sun. It shows how Macia's hands were tied to the rear of a police van behind his head before it moves off. Two hours later he was found dead in a cell, said the Independent Police Investigative Directorate (IPID). A postmortem gave the cause of death as head injuries and internal bleeding.
