Police were called to a property in Mulberry Walk at 8.17pm on Friday and discovered the body of a 41-year-old woman.
Formal identification of the woman is yet to take place but her next of kin have been informed.
Neighbours have described the discovery of the woman's body as 'shocking' and 'upsetting'.
A 42-year-old man was arrested on suspicion of murder and has been released on police bail until May 15.
Police are investigating the death as 'unexplained'.
A post mortem was carried out on the woman’s body yesterday but proved inconclusive, so toxicology tests have been requested by the pathologist.
A police cordon is still in place at the house.
