A former nurse, who was working with Thames Valley Police, has been charged with manslaughter following the death of a man in custody.

It follows an Independent Office for Police Conduct (IOPC) investigation into the death of William Cameron, 38, after he was taken into custody at Loddon Valley Police Station, near Reading, in 2020.

Sean Cregg, 35, who worked for Mountain Healthcare – a procured service provider for the force – has been charged with gross negligence manslaughter and a further charge under section 7 of the Health and Safety at Work Act 1974.

He is due to appear at Westminster Magistrates’ Court on 1 July.

Mr Cameron had been arrested and taken into custody on 8 January 2020 and died later that day in hospital.

The IOPC investigation began the same day and concluded in March 2021.

That month, it said it sent a file of evidence to the Crown Prosecution Service (CPS) to consider potential criminal charges.

“Following the referral, we received requests from the CPS for further material to assist with its decision-making,” it said.

Malcolm McHaffie, head of the CPS special crime division, said: “It is extremely important that there should be no reporting, commentary or sharing of information online which could in any way prejudice these proceedings.”

A police sergeant, who was also referred to the CPS, will not face charges, the IOPC said.

Both Thames Valley Police and Mountain Healthcare have been approached for comment.
