'Concerns were raised' about disgraced teacher

Jonathan Thomson-Glover admitted secretly filming pupils at the school

An email raising concerns about a teacher who made indecent films of pupils was sent to the school two years before his arrest, the BBC has learned.

Jonathan Thomson-Glover was jailed last week for secretly filming pupils at boarding school Clifton College.

It has emerged a parent raised concerns about his behaviour and said they had been told Thomson-Glover was found tied to a chair "in his underpants".

The college said it was going through "historic concerns" raised about him.

Last week Thomson-Glover, 53, of Wadebridge, Cornwall, admitted making indecent films of more than 120 pupils at Clifton College, Bristol, over a 16-year period.

He was jailed for three years and nine months, ordered to sign the Sex Offenders' Register indefinitely and was banned from working with children.

One parent raised concerns about Thomson-Glover's behaviour in 2012 in an email outlining a series of complaints to the college, seen by the BBC.

In it, "serious concerns" about Thomson-Glover's sexuality were mentioned along with a claim the teacher had been found tied to a chair in a state of undress.

At the time the school responded it would "look into the issues raised".

The Independent Schools Inspectorate said schools should immediately inform the local authority of allegations made against staff.

Bristol City Council said it had received "an allegation from a parent which stated that they had previously raised safeguarding concerns about Mr Thomson-Glover to Clifton College", after Thomson-Glover's arrest in 2014.

A Clifton College spokesman said: "In view of the facts which have and continue to come to light following Mr Thomson-Glover's arrest and prosecution, we are reviewing all matters relating to his time at the college and any historic concerns raised.

"All pertinent information has and will be passed on to the relevant authorities."
