An argument over a turn to rape a teenage girl ended in one of the attackers allegedly stabbing and killing his accomplice.

Now, a 22-year-old man stands accused of murder and rape.

He allegedly stabbed his friend Muzimkhulu Dlwathi in the upper body during the fight.

The incident happened in Oakmoor Extension 9 in Tembisa at the weekend.

Police spokeswoman Constable Patricia Mgijima said the two were at a party earlier at Teanong Section in Tembisa.

The victim was allegedly taken from the party by the deceased who said she would be his girlfriend for the night.

"He grabbed her and went with her to Oakmoor together with his friend. When they arrived at the house, they overpowered the teenager and raped her."

Mgijima said after the two took turns raping her, one of them tried to rape the girl again.

"The deceased decided to rape her again but his friend told him that he could not. A fight ensued between the two men.

"The suspect grabbed a sharp object and stabbed his friend in the upper body."

During the fight the girl managed to run away, Mgijima said.

The suspect then asked another friend to help him move the injured man to another place.

Mgijima said a resident alerted the police about the murder.

Dlwathi's family said that they were shocked that he was accused of rape.

Dlwathi's grandmother Anna, 83, said he was a sweet boy.

"I last saw him on Saturday when he returned from [a] family function, he did not say where he was going.

"A boy came here later that night and told us he was stabbed. He was found in a shack, naked with a stab wound in the neck.

"He was a sweet boy. I do not believe what they are saying about him. I am not defending him, but why did he kill him?"

His mother Dikeledi also did not believe the allegations against her son.

"That is not my Muzi; he has a girlfriend and we know her. It is painful, especially the way he died," Dikeledi said.

Dlwathi's uncle Steve said the rape allegations against his nephew were "just allegations".
