Matthew Mowbray, aged 49, of Locks Road, Locks Heath, was convicted today (25/11) at Reading Crown Court for the offences which occurred at the college between 2009 and 2019 and involved 11 victims.
On Wednesday (18/11), Mowbray pleaded guilty to six counts of making indecent images of children and one count of voyeurism.
However, today he has been found guilty by unanimous verdict of eight counts of sexual activity with a child.
A Thames Valley Police investigation began last year following a disclosure from one of the victims.
As part of the investigation, officers found thousands of indecent images of children in Mowbray’s possession, ranging from category A to C.
He had superimposed the faces of boys who were in his care onto some of these images.
Additionally, he sexually touched a number of male children in their bedrooms at the college.
Mowbray was charged with the offences on 3 March this year.
Investigating officer, Detective Constable Kathryn Webb, of the Child Abuse Investigation Unit, based at Windsor police station, said: “These convictions are a result of an 18 month investigation that was supported by a transparent working relationship with both Eton College and the local authority.
“The offences were committed whilst Matthew Mowbray occupied a position of trust which he betrayed.
“The victims and witnesses, many of whom are children, had the courage to come forward and provide evidence on very personal matters and in challenging circumstances.
“They should be commended for their bravery and take the credit for preventing Matthew Mowbray from committing any more offences against children.”
Mowbray will be sentenced at a future hearing.
