The police watchdog is to investigate 10 South Yorkshire Police officers over the handling of child sexual exploitation in Rotherham.

The officers are 10 of 13 referred to the Independent Police Complaints Commission (IPCC) by the force.

Two are not being investigated while a third officer remains under review.

A report, published by Professor Alexis Jay in August, found the abuse of 1,400 children in Rotherham over a 16 year period was ignored by agencies.

IPCC Commissioner Kathryn Stone said: "The amount of public concern across the country about this episode and the impact on confidence in the police means it is important that a fully independent investigation is conducted to establish how South Yorkshire Police dealt with child sexual exploitation.

"I sincerely hope that victims and their families will see this investigation as a positive step towards answering the many questions they must have."

The IPCC probe comes after a whistleblower told the BBC she had regularly passed details about alleged abusers to senior police officers but they had failed to act.

The 10 officers - some of whom are still serving with South Yorkshire Police - were identified in Professor Jay's report, which detailed how children had been subjected to trafficking, rape and other sexual exploitation between 1997 to 2013.

Allegations against them included failures to progress investigations into children being abused and the loss of evidence.

A spokesman for South Yorkshire Police said: "The force has met with the IPCC and remains absolutely committed to assisting them with their independent investigation in any way we can to ensure the full facts are established relating to any alleged misconduct.

"We will fully co-operative with the investigation into the force's handling of child sexual exploitation and anyone found to have not acted appropriately will be held to account."

The controversy that followed the report led to a series of high-profile resignations, including Rotherham's strategic director of children's services, Joyce Thacker, and South Yorkshire Police and Crime Commissioner Shaun Wright, who had been the councillor with responsibility for children's services between 2005 and 2010.
