A businessman wanted in South Africa over the honeymoon murder of his wife may only be moved to an open NHS rehabilitation ward if he does not pose a significant flight risk, a court has heard.

Shrien Dewani will only be moved from a secure mental health hospital after a change is made to his bail conditions.

Despite the agreement of psychiatrists that he should be moved in order to aid his recovery from depression and post-traumatic stress disorder, chief magistrate Howard Riddle told Westminster Magistrates' Court there is a possibility that his clinical needs will not determine where he goes.

"A very important factor was the assurance that Mr Dewani wanted to go back to South Africa as soon as possible," Mr Riddle said.

"There is a possibility Mr Dewani may not be moving for his clinical interest, but the Bail Act will determine where he goes."

The 32-year-old, accused of arranging the contract killing of his wife Anni in Cape Town in November 2010, is receiving treatment at a secure mental health hospital in Bristol after being sectioned.
