Police were called to the Poppyfields care home in Chapman Way, Eynesbury, just after 5pm on Monday night after concerns were raised about a man and woman, believed to be husband and wife, who were tenants at the facility. An ambulance was called to the care home, but the woman was pronounced dead at the scene. The man was taken to Hinchingbrooke Hospital where he received treatment but he was then arrested on suspicion of murder and taken to Parkside Police Station in Cambridge where he remains in custody. Cambridgeshire police have launched an investigation and confirmed that a post mortem examination was due to be held late on Tuesday afternoon. They were unable to confirm the identity of the woman as no formal identification has been carried out. The care home is managed by the Hanover Housing Association, but day-to-day care for the 34-bed facility is provided by Cambridgeshire County Council. A spokesman for Hanover told The Hunts Post that the news had been deeply shocking and staff were supporting police with the investigation. In a statement, the company said: Obviously the incident yesterday is deeply shocking. We dont know all the circumstances and are working with the authorities while they carry out their investigations. Our sympathies are very much with the family and friends of those involved. Police hope to be in a position to name the dead woman today (Wednesday).
