Hong Kong police seized hundreds of pictures in connection to a series of racy photos posted on the Internet that appear to depict partially nude local celebrities.

The management company of one of the stars Gillian Chung -- a member of the popular female duo Twins -- has said the photos were doctored.

The scandal over the photos has dominated headlines in Hong Kong the past week. The pictures appear to show actor Edison Chen, actress Cecilia Cheung and Chung partially nude or in sexually suggestive poses.

Police arrested six more people -- four men and two women -- late Friday and Saturday on suspicion of violating obscene material laws, assistant police commissioner Wong Fook-chuen said late Saturday.

Officers also seized computers and discs that contained hundreds of pictures, including some that have never been circulated on the Internet.

Wong said police "were very close" to arresting the sources of the photos.

The suspects arrested so far have not been charged and were being detained for further investigation, a police spokesman said Sunday, declining to be named citing internal policy.

Last week, police arrested and charged a 29-year-old unemployed man with publishing obscene material related to the case.

The stars have not directly commented on the photos, but have issued statements either through lawyers or management companies condemning their release.
