Teachers at Horncastle‘s prestigious grammar school were allegedly suspended amid claims pupils on a school trip were involved in under-age sex.
Parents of pupils at Queen Elizabeth’s Grammar School say they are shocked and concerned by reports of the events.
The News has been told two pupils - both under the age of 16 - had sexual intercourse after girls entered a “boys only” dormitory.
It alleged two other pupils - also aged under 16 - were involved in sexual activity in an adjoining room.
It is understood teachers who supervised the trip were asleep in a separate dormitory and were not aware of what happened.
No action was taken when the party of pupils returned to the school but QEGS was forced to intervene when pupils involved began to discuss events.
The News understands suspended teachers have returned to their duties.
The same source said letters were sent to parents of pupils who were on the trip.
One pupil told the News: “Everyone at the school is talking about what happened.
“It’s no big secret. It (sex) has gone on on other trips.”
One parent, who asked not to be named, added: “It is shocking that this sort of thing goes on.
“You think your children are safe when they go on an official trip.
“I am worried about letting my children go on trips and I know some other parents feel the same.”
The school has refused to confirm or deny the allegations.
The News e-mailed the school last Friday to ask headteacher Heather Payne for a comment. The school did not reply.
In a telephone call on Monday, the headteacher’s PA, Claire Cook, said the school would not be making any comment.
QEGS is one of the oldest and most respected schools in the country and consistently enjoys some of Lincolnshire’s top exam results.
It is a co-educational school and sixth form with Academy status. It has more than 800 pupils.
In an inspection in October 2009, Ofsted said: “Queen Elizabeth’s is a good and improving school, highly regarded by the local community.
“Its capacity to sustain improvement in the future is also good.
“The school’s specialism in science and mathematics is strongly felt.”
