A bright student was found dead in her room after going on an extreme diet to lose weight before going on holiday.

Lindsey Bone, 20, had been fasting and taking a weight loss supplement. The promising criminologist was described as a wonderful person.

The University of Sussex student was found dead in her bedroom in Coombe Road, Brighton, by flatmates on April 5.

She had died the night before.

At an inquest on Thursday a coroner could not find a reason for her death and said it was a "mystery".

Lindsey's mother Mandy Bone said: "She was just a wonderful, strong person.

"She wanted to get through university to honour her dad and do the best she could. She had so many plans for the future and everything she wanted to do."

Brighton and Hove Coroner Veronica Hamilton-Deeley heard Lindsey had been following a strict diet plan including fasting and regularly taking supplement tablets of apple cider vinegar, which is widely advertised as a "natural appetite suppressant" and "weight loss supplement" made from crushed, distilled and fermented apples.

The coroner was told by Lindsey's fiancé Jamie she had been anxious about an upcoming holiday and had been determined to lose weight.
