A former teacher in Bristol who filmed dozens of pupils using hidden cameras set up at a boarding school was jailed for more than three years yesterday.

Jonathan Thomson-Glover, 53, who taught at Clifton College, admitted 36 counts of making, taking and possessing indecent images of children.

Taunton Crown Court heard 130 victims were filmed by secret cameras at the school and an address in Cornwall over a 16-year period.

Thomson-Glover recorded more than 2,500 hours of footage to spy on pupils aged around 12 to 17 as they engaged in sexual activity and used the bathroom.

He was caught after the National Crime Agency (NCA) traced an IP address used for downloading indecent images of children to one of his four computers.

Police then discovered footage of pupils on his computers, as well as 330 VHS tapes and a number of Hi-8 tapes found at three addresses relating to him.

There is no suggestion Thomson-Glover, who described his filming as “a compulsion fuelled by the internet”, shared his footage or made physical contact with pupils.

Judge David Ticehurst jailed the former teacher for three years and nine months.

Searches were carried out at the home, the address in Cornwall and his term-time address at Clifton College.

Hundreds of VHS tapes were seized, as well as laptops, hard drives and discs, leading to officers discovering footage taken from covert cameras.
