Efforts to "swiftly" extradite fugitive Jack Shepherd are under way after he finally handed himself in to police in Georgia.
The 31-year-old surrendered at a police station in the nation's capital of Tbilisi on Wednesday - six months after he was convicted of killing 24-year-old Charlotte Brown from Clacton in Essex during a speedboat date on the Thames
The web designer was found guilty of manslaughter by gross negligence and sentenced to six years in prison in his absence, although he was controversially granted leave to appeal in December.
Ms Brown's family said they were overwhelmed with emotion after it emerged Shepherd had surrendered and her father said it was time for him to "atone" for his actions.
The Crown Prosecution Service is now preparing an extradition request to be lodged with Georgian legal authorities.
Home Secretary Sajid Javid said it is "vital Charlotte Brown's family see justice done" and UK law enforcement will "seek to swiftly extradite him to Britain".
