A police investigation into the unexplained death of a pensioner continues.

Officers were called to the home of 73-year-old Audrey McKenzie, of Kirby Malzeard, near Ripon, North Yorkshire, by ambulance crews on Saturday.

The woman was taken to Harrogate District Hospital, but died later.

Post-mortem tests proved inconclusive and detectives are yet to establish the cause of death, a police spokesman said. Further tests are now taking place.

An elderly man who was arrested on Saturday has been released on bail pending further enquiries.

"Investigating officers said the death is still unexplained at this time and they are keeping an open mind as to the circumstances," the spokesman added.
