Police officers have been cleared of contributing towards the death of a woman who died less than 48 hours after her release from custody in King's Lynn, it has emerged.

The findings appear in a report by the Independent Police Complaints Commission (IPCC) which concluded none of the actions of police officers led to the death of Kelly Curtis.

The 33-year-old was held at the Police Investigation Centre in Saddlebow after being arrested for affray in the early hours of November 2, 2014. She was also arrested for possession of Class A drugs.

Ms Curtis was assessed by the medical team, including psychiatrists, during her time in custody and later released on police bail. Her body was found at her home two days later and an inquest held in August last year concluded her death was alcohol and drug-related.

The IPCC report found the appropriate Mental Health Act assessments had been carried out, Ms Curtis received adequate support and that she did not need to be hospitalised.

It also states that the actions of officers and staff involved – including Sergeant Elizabeth Williamson, detention officer Chris Cutche and Special Constable Sarah Corner –had been 'appropriate in the circumstances'.

The report, released last year, concluded: 'This investigation has found no evidence that their actions could have influenced factors which led to the death of Ms Curtis.'

Norfolk Police declined to comment.
