The BBC's Social Affairs Correspondant Niall Dixon reports

The five-year-old girl was battered to death by her mother's boyfriend, despite the child's plight being reported to civilian and RAF police, and social workers.

Graham State, 25, was sentenced to life in jail - with a minimum of 25 years - after being convicted of murder.

Sharon Creed was given five years for cruelty

Her mother Sharon Creed was sentenced to five years after admitting two charges of child cruelty.

All agencies involved in the Lauren Creed inquiry accepted charges that they had failed to keep adequate records, failed to communicate and failed to hold a case conference.

But they said it had been difficult to get a "whole picture" of Lauren's circumstances because she had travelled to different areas of the country with her mother, who served in the Royal Air Force.

Nevertheless, David Lambert, from Norfolk Social Services, said: "A number of mistakes and errors, errors in subtle judgement, were made.

"These mistakes were not made wilfully or through negligence, but primarily because none of the agencies was aware of the whole picture."

Ken Williams: "Should have taken possession of that tape"

Chief Constable of Norfolk Police, Ken Williams, said it was "regrettable" that a tape recording of the youngster describing how she was beaten was not seized.

A neighbour, Sofiah Baker, became so concerned about the girl's battered state that she had taped her saying: "Daddy punched me in the belly today. Slapped me. Punched me."

Mrs Baker offered the tape to police who came to investigate a domestic incident at the girl's home - and wanted police to see how bruised the girl was.

"With hindsight we should have taken possession of that tape at the time," Mr Williams said.

He made assurances that the officers concerned had taken what they believed to be the appropriate course of action.

Sate was sentenced to life for Lauren's murder

"The officers believed Sharon Creed when she said the injuries were caused by smacking her bottom and her falling off a pedal cycle," he added.

David Wright, Chairman of Norfolk's Area Child Protection Committee, added that his staff were fighting "a growing tide of violence against children".

And he reiterated the words of Chief Constable Ken Williams when he said: "We must remember that it was Sate who killed Lauren."

He later said: "After an appalling tragedy such as this, people are bound to be angry.

"Worse than that, a child is dead. There can be no stricter judgement of out actions than that."
