A Limpopo man is accused of murdering his wife and threatening to assault his son.
The 48-year-old was arrested in the Tshaulu policing area in the Vhembe district.
Police spokesperson Brig Hlulani Mashaba said the couple's son arrived home at lunchtime on Saturday as his father was walking out of the gate. He greeted him and asked after his mother.
His father started to shout at him and allegedly threatened to beat him.
Mashaba said the son went to the two-roomed house to look for his mother but found the door locked.
