Two senior staff members have been suspended from a Sutton college following sex romp allegations.

Carshalton College confirmed it had launched an internal investigation after allegations that a man and a woman were caught having sex in the toilets and offices twice last month.

It was claimed the pair were caught by a student after they “sloped off’’ during a late-night French-themed awards dinner for staff.

It is alleged the couple were discovered a second time by a shocked colleague in a manager’s office on the evening of Thursday 11.

Carshalton College sales and publicity manager Andrew Stowell said an investigation into the allegations was still ongoing.

He said: “The college can confirm that two members of its staff have been suspended from duty pending an investigation into allegations that were made before Christmas.

“The investigation is on-going and, although started before Christmas, has been delayed due to the Christmas break.

“Naturally, no further information can be made available at this stage, until the College’s investigation is complete.’’ The claims came to light after two people contacted the Sutton Guardian through fears the incident would be “swept under the carpet’’.

The staff member, who did not want to be named, said: “It is absolutely inappropriate. They should know better.’’ A second source, who did not want to be named, said: “From my experience, the management at the college are quick to sweep things under the carpet.’’ Carshalton College, which offers a strongly vocational curriculum, had 4,300 students in 2007-08, of which 1,500 were full-time students aged 16 to 18 and 720 full-time adults.

It is claimed that one of the members of staff is married with children, but the other is not married. Both are believed to hold senior management positions.

It is not known if the teachers involved were among the 54 honoured at the bash which included French food and wine.

Principal David Watkins said: “Students should be taught and supported by professional staff who set a good example. If standards were compromised, the college will take swift and robust action.”
