A police spokesman said: "A 32-year-old man and a 24-year-old woman were arrested today in connection with the investigation into the circumstances surrounding the death of eight-year-old Charlotte Avenall from Mansfield. They are currently being questioned by police." He would not confirm the identity of the pair.

The parents were interviewed under caution by detectives at the time of Charlotte's death.

Mick Burrows, the chief executive of the authority, said at the time: "We are very sorry to hear of the death of this young girl. It is a tragedy. It is clear that our children's services had been involved with her family.

"We will investigate this matter thoroughly. We take the protection of vulnerable children very seriously. We were working with her family, who were receiving support from the county council and a number of other agencies."
