Johannesburg -

Shrien Dewani will appear in the Western Cape High Court on Friday, where an update on his mental health is expected.

This will be his third appearance on charges of conspiracy to commit kidnapping, robbery with aggravating circumstances, murder, kidnapping, and defeating the ends of justice.

The state alleges that he acted in common purpose and conspired with Cape Town residents Zola Tongo, Mziwamadoda Qwabe and Xolile Mngeni to kill his wife, Anni.

Dewani claimed he and Anni were kidnapped at gunpoint as they drove through Gugulethu in Cape Town in a taxi in November 2010.

The couple had been on honeymoon in the country. He was released unharmed, but his wife's body was found in the abandoned car the next day. She had been shot dead.

Dewani has not yet been asked to plead.

He appeared in court in May when it was decided that he would remain at Valkenberg Hospital in Cape Town to receive further treatment for his mental health.

Before being extradited to South Africa, Dewani had been detained in a hospital in Britain for depression and post-traumatic stress disorder. - Sapa
