“It is alleged the couple was returning from Bellville court over a domestic violence case against the police officer,” Ipid acting spokeswoman Grace Langa said in a statement.
The police constable allegedly used his service pistol to shoot the 37-year-old-mother of two.
“It is alleged that 15 gunshots were fired.”
The 36-year-old officer handed himself over to the Delft police where he was arrested.
The couple’s two children were in the house at the time.
“It is further alleged that there is a history of domestic violence between the couple,” Langa said.
