The Nottingham University Hospitals trust is already facing a police investigation over the deaths.
Social affairs correspondent, BBC NewsNottingham University Hospitals trust could be prosecuted over the deaths of the infants in 2021 by the Care Quality Commission .The trust said it was cooperating with the CQC.
On Thursday, Nottinghamshire police also said they were opening a criminal investigation into the trust's maternity services.The deaths the CQC are investigating occurred at the trust's City Hospital in April, June and July of 2021. An inquest into the death of Quinn Lias Parker, who died at just two days old in July 2021, found that a series of errors by the hospital had contributed to his death.
The BBC understands the other cases being examined by the CQC are the deaths of Adele O'Sullivan and Kahlani Rawson. She also found that a placental abruption was likely to have occurred hours earlier but that CTG scans had been "misinterpreted" by staff, which led to "reassurance" about the baby.
