Eleven people have been arrested on suspicion of manslaughter following the death of a woman shortly after she was moved from a care home.
Ivy Atkin, 86, died on November 22 last year, just after she had been moved following the closure of the Autumn Grange residential home in Sherwood Rise, Nottingham, police said.
Eleven people – five men aged 37, 44, 56, 64 and 77, and six women aged 19, 20, 25, 28, 29 and 52 – have been arrested on suspicion of manslaughter as part of the inquiry.
They will be questioned by detectives.
A Nottinghamshire Police spokesman said: “An investigation into the standard of care provided to residents at Autumn Grange is also under way and police are working closely with partner agencies to establish if any criminal offences took place.”
