The mother of a four-year-old boy found dead in a tumble dryer has been arrested on suspicion of child neglect, it has emerged.

Sonny Gibson’s body was found by his mother Anne Gibson and a police officer at her home in Ashbourne, Derbyshire, on July 26.

The boy is believed to have climbed into the tumble dryer during a game of hide-and-seek.

A spokesman for Derbyshire Police said a woman had been arrested in connection with the care of Sonny and not his death.

He said: “We have arrested a 41-year-old woman on suspicion of child neglect following investigations into the incident.”

Ms Gibson was arrested last Friday and was bailed.

Sonny was playing in his family’s garden shortly before he went missing.

His mother called police and a large-scale search, which included the force’s helicopter, was launched.

About 50 minutes later, Sonny was found dead in the tumble dryer by his “distraught” mother and a police officer.

Detectives have not said whether the dryer was switched on when the boy was found
