Three released after Lincoln death found to be from natural causes

Three people arrested after the discovery of a man's body in Lincoln have been released after a post-mortem examination found he died from natural causes. Lincolnshire Police said officers were called to Clifton Street shortly before 10.30am on Sunday after the body of a 55-year-old man was found. Following the discovery, two men aged 33 and 50 and a 54-year-old woman were arrested on suspicion of murder while enquiries were carried out. By Monday, the force said it had received the results of a post-mortem examination, which concluded the man had died from natural causes. Police said the three people who had been arrested would face no further action. The force said the death is no longer being treated as a homicide investigation. A file will now be passed to the coroner. Only limited details about the circumstances have been released. The Lincoln Post has not independently verified these claims. Lincolnshire Police's update means the investigation has changed direction since the initial response on Sunday, when officers began inquiries after the man's body was found at the property in Clifton Street. The street is in Lincoln, and the incident prompted an emergency response before the post-mortem findings were returned. The force has not released further information about the man. It has also not published additional details about the circumstances leading up to the discovery of the body. Police said the post-mortem result established that the 55-year-old died from natural causes, bringing the murder inquiry to an end. The case will now move into the coroner's process, which considers deaths in certain circumstances and records formal findings where required. At the outset of investigations into unexplained deaths, arrests can be made while officers establish the facts. In this case, Lincolnshire Police said the medical findings meant no criminal offence had taken place in relation to the death. The three people who were arrested have therefore been released with no further action, according to the force. No names have been published by police in connection with the incident, and there has been no further public statement giving more detail about the address or those involved. The latest information from Lincolnshire Police indicates that the man's death was due to natural causes rather than any unlawful act. The incident began with a report shortly before 10.30am on Sunday, and by the following day police said the post-mortem examination had clarified the cause of death. A coroner will now consider the case as part of the usual legal process that follows in such circumstances. This story was adapted by The Lincoln Post from original reporting by www.bbc.com.
