Isobel Narayan, the teenaged daughter of a judge was found dead in her home.

The 16-year-old was found by her parents in the bedroom of her family's £400,000 four-bedroom home in Didsbury, Greater Manchester, last Sunday, reports Mirror.

The cause of the death is not known and the circumstances also do not seem suspicious. However, tests are being carried out to check if her death was due to the Sudden Adult Death Syndrome (SADS).

SADS is a cardiac condition that can strike at any age. The cause of death in this condition is a massive disturbance in the heart's rhythm and it claims the life of about 500 people in Britain every year.

An investigation is going on in the matter.

Harry Narayan (66), Isobel's father, is a barrister at Cobden House Chambers in Manchester and sits as a crown court recorder and a part-time immigration judge.

The family of the girl is totally devastated and clueless about what happened to her.

We're absolutely devastated. We have no idea what happened, Harry told the Manchester Evening News.

Isobel was a very bright and popular student at school with a wide circle of friends. She reportedly gained 10 A* GCSE grades and an A grade in AS level maths earlier this year, reported the Daily Mail.

She had enrolled at Xaverian College in Manchester. A keen horse rider, Isobel was a member of Mobberley Riding School in Cheshire where she had received several awards.

Shortly before 12.25pm on Sunday, December 18 police were called to Mersey Meadows, Didsbury, following the death of a 16-year-old girl. Police attended and the girl was pronounced dead at the scene. There are no suspicious circumstances and the details have been passed to the coroner, said a spokesman for Greater Manchester Police.
