It's emerged that the full facts over how social services and other agencies dealt with Shannon Matthews' family in the years leading up to her abduction will never be made public - to protect Shannon and her siblings.
It's claimed that publishing the precise details of a serious case review into Shannon's kidnapping by her mother and uncle, would put the youngsters' welfare at risk. Lisa Adlam reports.
West Yorkshire Police have been called in to help investigate the disappearance of missing schoolgirl Tia Sharp.
Scotland Yard has confirmed it's asked for their help as there could be similarities with the Shannon Matthews case.
Nine-year-old Shannon Matthews was kidnapped by her mother and her partner's uncle in February 2008.
Tia, 12, has never run away before but vanished without a trace on Friday afternoon after telling relatives she was going shopping at the Whitgift Centre in Croydon.
Tia is thought to have been last seen at the house where her grandmother Christine Sharp, 46, lives with partner Stuart Hazell, 37, at The Lindens in New Addington, south-east London.
The 36 year old was sentenced to 8 years for false imprisonment and perverting the course of justice.
A former neighbour of Karen Matthews, jailed for faking her own daughter's disappearance has told a national newspaper that Karen insists there were several others involved in the plot, but she is too scared to reveal the truth. She said she wants to take a lie detector test to prove it.
