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.
"As is routine we liase with all forces that have dealt with similar cases. This case is like the Shannon Matthews case. This is a missing persons case and we are putting all our resources into finding her."
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.
