A Chinese woman who became an online sensation after posting a homemade pornographic film of herself on the internet has been detained in Shanghai, according to state media.

The 12-minute-video showed the woman, surnamed Huang, performing “sex acts,” the official China Daily said in its weekend edition, without elaborating.

“It soon became one of the most popular downloads on the mainland, with thousands of people downloading it last month,” the report cited the local police as saying in a statement.

The woman set up a blog, hoping to profit from her notoriety and sell interviews with herself for up to 30,000 yuan ($4,383) a time, the newspaper said.

Despite the police’s best efforts, the video is still available online, it added, without saying what penalty the woman may have to pay.

Pornography is illegal in China, although it is widely available on pirated DVDs throughout the country, and on the internet.

Warner Music Group ordered YouTube on Saturday to remove all music videos by its artists from the popular online video-sharing site after contract negotiations broke down.

The order could affect hundreds of thousands of videos clips, as it covers Warner Music’s recorded artists as well as the rights for songs published by its Warner/Chappell unit, which includes many artists not signed to Warner Music record labels.

The talks fell apart early on Saturday because Warner wants a bigger share of the huge revenue potential of YouTube’s massive visitor traffic. There were no reports on what Warner was seeking.
