'Body found' in search for missing author Helen Bailey

Detectives probing the disappearance of author Helen Bailey say they have found what is believed to be a body in the grounds of her home.

The 51-year-old children's novelist, who wrote the Electra Brown novels, was last seen walking her dog on April 11.

Specialist teams had been searching her property in Royston, Herts, since Monday, Hertfordshire Police said.

A 55-year-old local man arrested on Monday on suspicion of murder was re-arrested on Thursday and is being questioned in Stevenage.

Detective Chief Superintendent Paul Fullwood, who leads the Bedfordshire, Cambridgeshire and Hertfordshire major crime unit, said: "Helen's family have been updated of this significant development and are continuing to receive support from specialist family liaison officers."

Ms Bailey was last seen several weeks after the fifth anniversary of the death of her husband, John Sinfield, who drowned on a holiday in Barbados in February 2011.
