Dr Raghavjee, a 60-year-old GP, was on his way home in King’s William Town, when he was carjacked and murdered in November 2007.
Robbery was ruled out as a motive after his mobile phone, 500 Rand (£45) in cash and watch were left at the scene.
Peter Shaya, a friend of the Raghavjee family, said in 2008: “It shows that it was a well organised crime because these people left no clues behind."
Yesterday, Captain Thozama Solani, King William’s Town police spokesman, confirmed that Dr Raghavjee’s case was being looked at again.
“We can confirm that the investigations are on again in the case of Dr Pox,” said Solani.
