This is what we know so far after police launched an investigation into the death of a woman in Colchester.
A man, 51, was being quizzed by detectives after a 50-year-old woman was found unresponsive at a property.
She was pronounced dead at the scene.
Detectives are no longer treating the death as suspicious.
Essex Police had been called with concerns for a woman inside a property in Lilianna Road, on the Chesterwell estate, shortly before 9.10am on Tuesday.
Emergency services attended and a woman in her 50s was pronounced dead at the scene.
A forensic post-mortem examination was carried out today and found there were no signs anyone else had been involved in her death.
A 51-year-old man, initially arrested on suspicion of murder, has been released without charge.
An Essex Police spokesman said: "A file will be prepared for the coroner.
"Our officers continue to support the woman’s family at this difficult time."

Colchester councillor David King has lived on the Chesterwell estate for several years.
"The estate is only four or five years old and these are new houses," he said.
"It is a new development in a nice setting, with woodland down one side and a country park down the other.
"This is a lovely place for people to make a start in north Colchester and there is a nice community atmosphere.
"Many have come to start a new life or family.
"There is always a sense of shock whenever there is a loss of life."
One couple, who only moved to the estate at the end of January, said: "The most shocking part is when we were trying to buy our house we met this woman, she was very nice.
"She seemed like a lovely woman.
"She just said she used to work as a nurse and her husband used to work in the police."
Anyone with information should call 101 quoting incident 283 of February 16.
