North Yorkshire Police have named the woman who died at a flat in Trafalgar Square, Scarborough, on Tuesday as Samantha Johnson, aged 28, from Scarborough.
A police spokesman said an inquest would take place into her death, however he said no date had been set.
He added: “She was 28 and not in her mid-forties as originally believed. Apologies for the confusion this may have caused.
Ms Johnson was declared dead by paramedics at just after 11pm on Tuesday (March 25).
A 37-year-old man who was arrested in connection with the death has now been released on bail, pending further enquiries.
Police officers were called to the flat by the ambulance service following the death which was described by police as sudden and unexplained.
