The grandmother of missing schoolgirl Tia Sharp has been arrested on suspicion of murder.
Christine Sharp, aged 46, was detained following the discovery of a body at her home in New Addington, near Croydon, south London, on Friday.
Her partner Stuart Hazell, 37, was arrested on Friday night on suspicion of murder.
Ms Sharp’s next-door neighbour Paul Meehan, 39, was later taken into custody on suspicion of assisting an offender.
In the wake of Mr Hazell’s arrest, Scotland Yard announced that a 46-year-old woman and 39-year-old man had also been arrested.
Sources later identified the two further suspects as Ms Sharp and Mr Meehan.
Tia’s biological father, Steve Carter, is from Moulton and had been helping search for his daughter.
