Helen Barker, a former MasterChef contestant, has died suddenly at the age of 38.
Wiltshire police received a call at 9.07am on 8 September reporting a sudden death at an address in Trowbridge.
A 78-year-old man was arrested the same day on suspicion of manslaughter and assault occasioning actual bodily harm and taken to Melksham custody, and was released on bail on Friday.
A post mortem has been carried out and the result was inconclusive. Further pathological tests will be required.
It is believed Barker took part in the 2006 MasterChef competition.
Barker's family have released a tribute, which reads: "The whole family have been left devastated by Helen's untimely death. She was much loved and will be greatly missed by us all. She was a bright young woman who, in addition to her attainment of a BSc degree in Dental Technology at the University of Wales Institute Cardiff, was a talented artist and an accomplished cook, having appeared on the MasterChef television programme.
"It will be difficult to come to terms with her loss, but this is being aided by the kind words and messages of support we have received and for which we are very grateful."
