Accused New Zealand mosque gunman Brenton Tarrant plans to represent himself in court—raising concerns he could attempt to turn a trial into a platform for his beliefs.

Richard Peters, the duty lawyer who represented Tarrant in court on Saturday, confirmed to The New Zealand Herald that he was no longer acting for him.

Peters said Tarrant appeared to be lucid and was not mentally unstable—other than the extreme views that he held.

The attorney said that his job representing Tarrant ceased on Saturday, and that the accused gunman had told him he wanted to represent himself in future.

The next court hearing is scheduled for April 5.
