The house is less than 100 yards from Manor House, where Prince William moved on his arrival at Eton. The boy died as other pupils slept in a nearby dormitory.
An ambulance was called but the boy was certified dead in his room by a police surgeon. The death was announced at morning assembly and several boys were later interviewed by police. The dead boy was a second-year pupil at the school, where he had been studying since September 1997.
His parents were yesterday at the college, being comforted by the headmaster, John Lewis. A police spokesman at Slough, Berkshire, said that there were no suspicious circumstances. The police spokesman did not name the boy, whose body was taken to Wexham Park Hospital in Slough. The death will be investigated by the East Berkshire Coroner.
Mr Lewis said that the boy had been an excellent pupil who appeared to be making good progress in his work and at games. "He enjoyed the company of others and was much respected by them. The school's sympathy goes out at this time to the boy's parents and his family and friends," the headmaster said.
Last night the school flag flew at half mast.
