New Zealand Police have announced they believe missing British backpacker Grace Millane has been murdered, BBC reports.
The 22-year-old from Essex - described by her father as "lovely" and "family-orientated" - was last seen in New Zealand a week ago.
Det Insp Scott Beard said the evidence told them she was "no longer alive".
A 26-year-old man - who was with Miss Millane before she went missing - is being held in Auckland in connection with the murder.
"Grace's family have been advised of this development and they are devastated," Det Insp Beard added.
The announcement follows a review of CCTV footage, the forensic examination of a hotel where she was last seen on Saturday 1 December, and the discovery of a vehicle.
