The police watchdog will investigate the care given by police in Hull to a woman who became seriously ill after being in custody.
The 22-year-old woman was arrested on 25th October and taken to hospital before being detained at Clough Road police station in Hull.
Humberside police told the Independent Police Complaints Commission (IPCC) that the woman was later examined and assessed before she was sectioned under the Mental Health Act.
She was then transferred to a mental health unit in Hull from where, some days later, she was taken to hospital in a seriously ill condition.
The independent IPCC investigation will examine the care provided to the woman, the supervision she was placed under and any other evidence available, including medical assessments.
Cindy Butts, the IPCC’s Commissioner for Humberside, said: “I have determined that an independent investigation is necessary to determine if the care provided during this woman’s custody was of an adequate standard and if any more could have been done to highlight any medical concerns prior to her transfer to a mental health facility.”
