Police in South Africa says more than 130 people have been arrested as part of an investigation into last week’s gang rape at an abandoned mine in Gauteng province. The previous figure given for the number held was just over 80. SA media reports that a group of women was attacked while filming a music video. Forensic evidence is still being checked and no rape charges have been brought yet. Most of those arrested have been appearing in court on immigration charges, having allegedly entered South Africa illegally from neighbouring Lesotho.
