Shrien Dewani boarded a first-class flight out of South Africa after his trial for killing wife Anni Dewani collapsed.

Dewani, 34, was believed to be flying back to Britain via Dubai from Cape Town international airport. He refused to answer questions from a media scrum waiting for him.

Officials from the British Consulate in Cape Town ushered Dewani past the check-in desk and straight to the international departures lounge.

However new reports suggest Dewani's late wife's family are considering civil action against him, despite the collapse of his trial.

Anni's uncle, Ashok Hindocha, said her family had been lied to by Dewani and now they were considering "all the options presented to us".

"Shrien Dewani has lied to us from day one," he told Radio 4. "We went to South Africa with a lot of questions, to seek for answers; now we are coming home with more questions and more sleepless nights."

Dewani was freed from the trial when the judge ruled he could be discharged as there was no possibility of conviction unless he incriminated himself in the witness box.

The quality of prosecution witnesses was also criticised by judge Jeanette Traverso in her ruling.
