The body of a woman was found on the dump site of a school in Eldorado Park, south of Johannesburg, on Wednesday, Gauteng police said.
The 30-year-old woman had a stab wound to her upper body and her pants had been pulled half way down, warrant officer Kay Makhubela said.
The woman's body was discovered in Eldorado Park, Extension four, by a passerby.
Makhubela said five men who were last seen with the woman on Tuesday had been taken in for questioning. - Sapa
