A 51-year-old man wanted for an attack on his estranged wife and the murder of her son is no longer in Limpopo, provincial police said on Friday.
"We are dealing with an intelligent man, he is evasive. He is not in Limpopo, but we are closing his space bit by bit and we will grab him," Brigadier Hangwani Mulaudzi said.
"We have beefed up the team of detectives and trackers. We are working together with the Hawks and I am confident he will be arrested."
Mulaudzi said there were reasons to suspect someone was feeding him with information.
He dismissed reports that he was seen in Kimberley in the Northern Cape.
The man, whose identity document indicates he was born in Namibia, allegedly forced three men, believed to be his workers, at gunpoint to gang-rape his estranged wife and mutilated her in his home in Modimolle on Tuesday.
He then lured his 19-year-old stepson to his house and shot him dead when he arrived.
The man fled in his white Toyota Fortuner, registration number DCS 392 FS. The three workers ran away and their whereabouts were unknown.
Mulaudzi said the woman was taken to hospital for observation on Thursday.
"We took her to hospital. She was not feeling well and we hope she will be discharged today [Friday]." (Sapa)
