A pupil at one of Britain’s most prestigious boarding schools has been expelled after allegedly turning up at a Sunday chapel service on ecstasy.

The 16-year-old was rushed to hospital from Fettes College in Edinburgh after teachers noticed he was acting in an agitated manner.

The student, who had only joined the £33,000-a-year boarding school this term, was later reported to police.

Geoffrey Stanford, headmaster at Fettes College, said that the incident “has shocked both pupils and staff”, adding that the school are treating it “very seriously”.

The student involved in last Sunday's incident had only been at the school just over a week, joining at the beginning of the autumn term on August 30.
