Former Minneapolis policeman Derek Chauvin on Thursday waived his right to testify to the jury at his murder trial for the deadly arrest last May of George Floyd.

“I will invoke my Fifth Amendment privilege today,” Chauvin said after briefly removing his mask, referring to the constitutional right against self-incrimination, in his most extensive remarks since his trial began with jury selection on March 8.

The defence told Hennepin County District Judge Peter Cahill it would call no more witnesses after two days of testimony and would rest its case, which has focused on raising doubts about the cause of Floyd’s death.
