A man arrested then released over the death of his wife has said she took her own life as he spoke of "the worst days" of his life.
The body of dentist Dr Helen Nicoll, 53, was found at her house in Frog End, Great Wilbraham, Cambridgeshire, by police last Friday.
Her husband and business partner Stephen Nicoll, 53, was arrested on suspicion of murder but later released without charge by Cambridgeshire Police. A post-mortem examination found Mrs Nicoll died from asphyxiation.
Today Mr Nicoll issued a statement, saying: "These last few days have been the worst of my life.
"Nobody can understand the true loss that my children and I have experienced following the discovery that my wife Helen has taken her own life.
"We have fully co-operated with the police investigation and the matter has now been referred to the coroner.
"Whatever questions remain surrounding the circumstances of Helen's death, I would ask everybody, particularly the media, to respect our privacy and allow us to come to terms with our devastating loss and to begin the grieving process as a family following this tragedy."
His solicitor Paul Oliver, from Stokoe Partnership, said: "The arrest of Mr Nicoll in the immediate aftermath of the death of his beloved wife and the consequential media interest in this tragic case compounded the distress caused to him and his family.
"The police have confirmed Mr Nicoll is not a suspect and he and his family now ask that their right to grieve in private be respected."
The couple had three children. Both were partners at a private dental practice in Hurst Park, Cambridge, and he also worked in Harley Street.
