South African police are investigating allegations of sexual assault prior to the killing of white supremacist leader Eugene Terreblanche.
A lawyer for one of the two accused men said Terreblanche tried to have sex with at least one of the defendants.
Mr Terreblanche's body was found on a bed with his trousers pulled down. Police had initially said the killing was over a wage dispute, but are now exploring the possibility that the killing was an act of self-defence.
Puna Moroko, the lawyer representing one of the accused men - 28-year-old Chris Mahlangu - told South Africa's Sunday Times newspaper the attack was triggered by a sexual assault.
"My instructions from my client are that there was some sodomy going on and it sparked the murder of Mr Terreblanche," he said.
