Police in West Yorkshire investigating the disappearance of nine-year-old Shannon Matthews have arrested her mum.
Karen Matthews, aged 32, was arrested in Dewsbury late on Sunday night.
She has been arrested because it's thought she might have got in the way of the inquiry into Shannon's disappearance.
The uncle of Shannon's stepfather, Michael Donovan, has been charged with taking Shannon away.
Shannon, nine, went missing on 19 February. She was found less than a mile from her home in Dewsbury, West Yorkshire, three weeks later.
Two members of Shannon's family, her stepfather's mum - Alice Meehan, 49 - and his sister Amanda Hyett, 25, were arrested on Friday.
Mrs Hyett was arrested on suspicion of helping an offender, and Ms Meehan was arrested on suspicion of getting in the way of the inquiry into Shannon's disappearance.
They were both later given bail, which means that the police have allowed them to go home, while further investigations are carried out.
