Sin Chung-kai, a Legislative Council member representing information technology functional constituency, called on computer repair shops to carefully handle clients' data.

Still, the police's arrests in its recent investigation have made many Hongkongers worry that it is illegal to store obscene data on their computers, Sin said.

The Legislative Council's Information Technology and Broadcasting Panel will hold a special meeting after the lunar new year to ask for the police's explanation on the arrests.

Solicitor Vitus Leung Wing-hang, said it isn't against the law to store obscene data or share the data point-to-point.

It would also be legal, he said, for people to share obscene materials with adults, or upload the data to websites indicating they would contain sexual content.

"But a person would be in breach of the Control of Obscene and Indecent Articles Ordinance if he or she publishes obscene materials publicly - such as on an open forum for all ages - as youths under 18 could access them," Leung said.
