Hong Kong has been gripped by another photo scandal, after racy images featuring policewomen were taken from a blog and splashed across the territory's newspapers.

The photographs - which numbered more than 100 - showed Hong Kong policewomen touching a colleague's breasts, dressed in their underwear, pointing guns at each other and pulling up their skirts.

'Diary of a policewoman' ... the photographs numbered more than 100.

They were uploaded onto the personal blog of a 25-year-old female constable who joined the force in 2007, officials said.

Media coverage of the blog - called "the diary of a policewoman" - prompted local authorities to launch an internal inquiry.
