Four people are due to appear in court in Hankey on Wednesday in connection with a double murder over the weekend.
The arrests brings to seven the number of suspects behind bars for the murders for 41-year-old Claudia Antonie and 6-year old Lukishia Plaatjies.
Their bodies were found in a house at Rosedale in Hankey on Sunday morning after the assailants set it alight.
Meanwhile, two men and a woman appeared in court in Hankey on Tuesday in connection with the case.
Charges were however withdrawn against another woman.

He says both men indicated that they will not apply for bail.
Seekoei says the case against twenty-one year old Rina Pietersen was postponed to the 11th of August for a formal bail application.
