Embarrassed by some risque and juvenile postings, the police force will issue new guidelines this year for officers' use of the internet.
Police Commissioner Andy Tsang Wai-hung said the guidelines were necessary because some police officers had misused social media websites.
'We emphasise that we expect our officers to uphold a high standard of conduct and discipline, regardless of whether they are in a physical environment or in a virtual environment,' he said yesterday.
In a recent case, a female officer put up on her blog racy pictures of policewomen pulling up their skirts, pointing handguns at each other and touching one another's breasts.
'You will no doubt agree with me that such behaviour is not acceptable to the police force or the community,' Tsang said.
He said whatever officers did inside or outside Hong Kong would be subject to the same standard. Officers should uphold good discipline so as not to bring the force's image into disrepute, he said.
