Wilson, 20, from Heinz Park, faces 15 charges including six counts of murder, three counts of attempted murder, rape and assault with intent to do grievous bodily harm.
Last week, Wilson testified he was smacked and had his life and that of his family threatened if he did not sign a warning statement when he was arrested on 28 April 2015.
“I was then told to sign a form with my name on and it said murder at the top. I signed because I was scared,” he said.
“I was in the holding cells; I was taken out and smacked again by a detective. I don’t know why I was smacked.
“Nobody told me why I was there. No one explained to me what I was signing or read me my rights.”
But Captain John Pokemon of Nyanga Police Station, who arrested Wilson, says all procedures were followed when Wilson was arrested.
“We got full co-operation from the accused when he was arrested and I explained his rights to him, which is mandated. I spoke to him in Afrikaans and he understood,” he told the court.
“We went straight to the police station where the accused [Wilson] was booked into the holding cells. Again, I read him his rights and explained it to him and the accused signed saying he understood.”
Pokemon denied Wilson was assaulted.
“There is no way he could have been assaulted or threatened in my presence. He gave his full co-operation so why did he have to be threatened?” he said.
“If that had to happen, I would have allowed the accused to lay charges against whoever threatened or assaulted him.”
The trial resumes today.
