"He has filmed hundreds of women since 2008. They came to the monk to be blessed with holy water, but they were secretly filmed," said Police Chief Touch Naruth.

The man has been charged in Cambodian court with "producing and distributing pornographic images," prosecutor Ek Chheng Huot told Agence France-Presse.

Khai allegedly captured the footage at a temple, where women could come to use the pagoda bathroom for the religious ceremony.

"His act affects other monks and Buddhism and seriously harms our tradition," Naruth said.

Khai, who has been stripped of his religious status, faces up to a year in prison.
