Ashley Yates admitted six counts of voyeurism and three counts of making indecent images
A primary school head teacher who used a spy pen to film pupils in the toilets at his school has been jailed for two years and eight months.
Ashley Yates, 45, of Filton, used the device to record images in the toilets of The Tynings Primary School in Staple Hill, South Gloucestershire.
He admitted six counts of voyeurism and three of making indecent images of children at Bristol Crown Court.
The offences relate to seven girls, two boys and six adults.
They came to light after a child found a pen inside a disabled toilet at the school and handed it in to a caretaker.
