Becky Godden's mum starts petition to change arrest code

The mother of a woman whose body was found during the hunt for murdered Swindon office worker Sian O'Callaghan has set up a petition calling for a change in the law.

Christopher Halliwell led police to Becky Godden's body shortly after he confessed to killing Miss O'Callaghan.

But he was not prosecuted over Miss Godden's death after a judge ruled detectives ignored arrest guidelines.

Miss Godden's mother, Karen Edwards, told BBC Breakfast: "I feel there should be more flexibility when police officers arrest people."

The petition calls for an urgent review of the Police and Criminal Evidence Act.
