( dpa )- Police in Hong Kong were Wednesday trying to trace internet pranksters who posted bogus explicit pictures of prominent pop stars onto blog sites.
The pictures - reproduced on the front pages of Chinese-language newspapers - included video shots apparently showing singer Gillian Chung and her ex-boyfriend singer and actor Edison Chen naked on a bed together.
Separately, doctored pictures of Chung's head pasted onto the semi-naked body of another woman were posted online and widely picked up by the city's mass-market newspapers.
A police spokesman said the Commercial Crime Bureau was Wednesday investigating two cases of publishing indecent articles on the internet although no one had so far been arrested.
The management company for Edison Chen was also reportedly seeking legal advice over the bogus image which a spokesman for the company described as being "more likely a joke in bad taste."
Gillian Chung was embroiled in a controversy in 2006 when a magazine published sneakily-taken photographers of her changing clothes backstage at a concert in Malaysia.
