A former Chinese broadcaster has been found guilty of having more than 800 extreme porn videos which included footage of women being tortured.
Sen Luo, 40, of Park Avenue, Dover, Kent, was convicted at the Old Bailey of possessing extreme pornography.
Police discovered the porn by accident during an unrelated inquiry.
Suspicions were raised when Luo refused to answer the door of a house in Copethorne Road, East Grinstead, West Sussex, where he was living.
Jurors found Luo guilty of two counts of possessing the videos by a majority of 11-1.
Judge Charles Wide said Luo had amassed an enormous amount of extreme pornography over a period of time.
After the hearing, Det Con Kim Negus, of City of London police said she had to view the videos with the sound turned down because of the screams of the women.
She said: "These videos were disgusting and distressing. I viewed around 18 of them and had to have the sound down.
"They featured oriental women but it is impossible to say how they came to be used for these images."
Luo, who also used the name Edward Law, had claimed the images were part of research for a Chinese Sex and the City-style book.
He said he thought it would be a way of making money after fleeing China, where he presented a television programme on economics in 2008.
