Police are investigating the death of a baby girl who died within 24 hours of being born at a Manchester hospital.

Polly Lindop passed away at St Mary’s Hospital on 13 March.

Greater Manchester Police said on Monday that following “careful consideration” the baby’s death is being investigated for “possible gross negligence manslaughter” after concerns were raised to the force, as well as the coroner.

Paying tribute to their daughter, Polly’s family said: “As Polly’s parents we would like to thank everyone at GMP for their continual efforts every day in gaining us answers. Our beautiful brave baby girl Polly, we love you and miss you every day. Sleep tight my darling.”

DCI Mark Davis, of GMP’s major incident team, said: “First, I want to express my condolences to the parents of Polly at what is an extremely difficult time for them. Our thoughts will remain with them as we carry out our investigation.

“A number of hospital staff have been spoken to as witnesses by officers and no arrests have been made at this time.

“The hospital trust has been fully cooperative with the police and all relevant authorities have been kept informed.

“The investigation into Polly’s death is ongoing and her family will continue to be kept updated in relation to any significant developments.”

A spokesperson for Manchester University NHS Foundation Trust (MFT) said: “GMP is investigating an incident that happened in March 2023. Our thoughts continue to be with the family and we are cooperating fully with the police investigation.”
